Scientists at the University of Sussex have invented a ground-breaking new method that puts the construction of large-scale quantum computers within reach of current technology.
Quantum computers could solve certain problems – that would take the fastest supercomputer millions of years to calculate – in just a few milliseconds.
They have the potential to create new materials and medicines, as well as solve long-standing scientific and financial problems.
Universal quantum computers can be built in principle – but the technology challenges are tremendous. The engineering required to build one is considered more difficult than manned space travel to Mars – until now.
Quantum computing on a small scale using trapped ions (charged atoms) is carried out by aligning individual laser beams onto individual ions with each ion forming a quantum bit.
However, a large-scale quantum computer would need billions of quantum bits, therefore requiring billions of precisely aligned lasers, one for each ion.
Instead, scientists at Sussex have invented a simple method where voltages are applied to a quantum computer microchip (without having to align laser beams) – to the same effect.
Professor Winfried Hensinger and his team also succeeded in demonstrating the core building block of this new method with an impressively low error rate at their quantum computing facility at Sussex.
Professor Hensinger said: “This development is a game changer for quantum computing making it accessible for industrial and government use. We will construct a large-scale quantum computer at Sussex making full use of this exciting new technology.”
Quantum computers may revolutionise society in a similar way as the emergence of classical computers. Dr Seb Weidt, part of the Ion Quantum Technology Group said: “Developing this step-changing new technology has been a great adventure and it is absolutely amazing observing it actually work in the laboratory.”
A mid-air display of ‘floating pixels’ has been created by scientists.
Researchers at the Universities of Sussex and Bristol have used soundwaves to lift many tiny objects at once before spinning and flipping them using electric force fields.
The technology – called JOLED – effectively turns tiny, multi-coloured spheres into real-life pixels, which can form into floating displays or bring computer game characters to life as physical objects.
To be presented next week at a future technologies conference in Japan, the research opens up new possibilities for mobile and game designers, giving them a new way of representing digital information in a physical space.
Professor Sriram Subramanian, in the University of Sussex’s School of Engineering and Informatics, is the head of lab behind the research. He says: “We’ve created displays in mid-air that are free-floating, where each pixel in the display can be rotated on the spot to show different colours and images.
“This opens up a whole new design space, where computer and mobile displays extend into the 3D space above the screen.”
The pixels are levitated using a series of miniature ultrasound speakers that create high-pitched and high-intensity soundwaves that are inaudible but forceful enough to hold the spheres in place.
A thin coating of titanium dioxide gives the pixels an electrostatic charge, enabling them to be manipulated in mid-air by changes to an electric force field, created by tiny electrodes.
Dr Deepak Sahoo, Research Associate in Human-Computer Interaction at the University of Sussex, said: “The most exciting part of our project is that we can now demonstrate that it is possible to have a fully functioning display which is made of a large collection of small objects that are levitating in mid-air.
“JOLED could be like having a floating e-ink display that can also change its shape.”
The paper is the first to demonstrate such a fine level of control over these levitating pixels, moving the technology closer to something that might soon be part of theme parks or galleries.
For example, in the future such a display could be placed in a public park to show to users the complex and changing patterns of carbon footprints of different countries or currency fluctuations in different regions of the world. This could allow the general public to clearly see the multi-dimensional data and interact with it.
Asier Marzo, research associate in the Department of Mechanical Engineering at the University of Bristol, explained: “Traditionally, we think of pixels as tiny colour-changing squares that are embedded into our screens. JOLED breaks that preconception by showing physical pixels that float in mid-air.
“In the future we would like to see complex three-dimensional shapes made of touchable pixels that levitate in front of you.”
Professor Subramanian added: “In the future we plan to explore ways in which we can make the display multi-coloured and with high colour depth, so we can show more vivid colours.
“We also want to examine ways in which such a display could be used to deliver media on-demand. A screen appears in front of the user to show the media and then the objects forming the display fall to the ground when the video finishes playing.”
The elusive and complex components of creativity have been identified by computer experts at the University of Kent.
Dr Anna Jordanous, lecturer in the School of Computing, worked with language expert Dr Bill Keller (University of Sussex) on how to define the language people use when talking about creativity, known in the field as computational creativity. With that knowledge it becomes possible to make computer programs use this language too.
Dr Jordanous and Dr Keller looked at what people say when they talk about “what is creativity” in academic discussions, from various disciplines – psychology, arts, business, and computational creativity.
In an article entitled Modelling Creativity: Identifying key components through a corpus-based approach, published by PLOS ONE, they describe a unique approach to developing a suitable model of how creative behaviour emerges that is based on the words people use to describe it. Computational creativity is a relatively new field of research into computer systems that exhibit creative behaviours.
Using language-analysis software they identified the creative words and grouped them into clusters. These are considered to be 14 components of creativity. These clusters have been used to evaluate the creativity of computational systems, and are expected to be a useful resource for other researchers in computational creativity, as well as forming a basis for the automated evaluation of creative systems.
A prototype for an interactive mobile device, called Cubimorph, which can change shape on-demand will be presented this week at one of the leading international forums for robotics researchers, ICRA 2016, in Stockholm, Sweden [16-21 May].
The research led by Dr Anne Roudaut from the Department of Computer Science at the University of Bristol, in collaboration with academics at the Universities of Purdue, Lancaster and Sussex, will be presented at the International Conference on Robotics and Automation (ICRA), the IEEE Robotics and Automation Society’s biggest conference.
There has been a growing interest toward achieving modular interactive devices in the human computer interaction (HCI) community, but so far existing devices consist of folding displays and barely reach high shape resolution.
Cubimorph is a modular interactive device that holds touchscreens on each of the six module faces and that uses a hinge-mounted turntable mechanism to self-reconfigure in the user’s hand. One example is a mobile phone that can transform into a console when a user launches a game.
The modular interactive device, made out of a chain of cubes, contributes towards the vision of programmable matter, where interactive devices change its shape to fit functionalities required by end-users.
At the conference the researchers will present a design rationale that shows user requirements to consider when designing homogeneous modular interactive devices.
The research team will also show the Cubimorph mechanical design, three prototypes demonstrating key aspects – turntable hinges, embedded touchscreens and miniaturisation and an adaptation of the probabilistic roadmap algorithm for the reconfiguration.
Dr Anne Roudaut, Lecturer from the University’s Department of Computer Science and co-leader of the BIG(Bristol Interaction Group), said: “Cubimorph is the first step towards a real modular interactive device. Much work still needs to be achieved to put such devices in the end-user hands but we hope our work will create discussion between the human computer interaction and robotics communities that could be of benefit to one another other.”
An international team of scientists has set a new record for the complexity possible on a quantum computing chip, bringing us one step closer to the ultra-secure telecommunications of the future.
A key component of quantum science and technology is the notion of entangled particles – typically either electrons or particles of light called photons. These particles remain connected even if separated over large distances, so that actions performed by one affect the behaviour of the other.
In a paper, published today in the journal Science, the research team outlines how it created entangled photon states with unprecedented complexity and over many parallel channels simultaneously on an integrated chip.
Importantly, the chip was also created with processes compatible with the current computer chip industry, opening up the possibility of incorporating quantum devices directly into laptops and cell phones.
The researchers were led by Professor David Moss, the newly appointed Director of the Centre for Micro-Photonics at Swinburne University of Technology, and Professor Roberto Morandotti from the Institut National de la Recherche Scientifique (INRS-EMT) in Montreal, Canada.
The researchers used ‘optical frequency combs’ which, unlike the combs we use to detangle hair, actually help to ‘tangle’ photons on a computer chip.
Their achievement has set a new record in both the number and complexity of entangled photons that can be generated on a chip to help crack the code to ultra-secure telecommunications of the future.
It also has direct applications for quantum information processing, imaging, and microscopy.
“This represents an unprecedented level of sophistication in generating entangled photons on a chip,” Professor Moss says.
“Not only can we generate entangled photon pairs over hundreds of channels simultaneously, but for the first time we’ve succeeded in generating four-photon entangled states on a chip.”
Professor Morandotti says the breakthrough is the culmination of 10 years of collaborative research on complementary metal–oxide–semiconductor (CMOS) compatible chips for both classical and quantum nonlinear optics.
“By achieving this on a chip that was fabricated with processes compatible with the computer chip industry we have opened the door to the possibility of bringing powerful optical quantum computers for everyday use closer than ever before,” Professor Morandotti says.
The groundwork for the research was completed while Professor Moss was at RMIT. The collaboration includes the City University of Hong Kong, University of Sussex and Herriot Watt University in the UK, Yale University, and the Xi’an Institute in China.
