Part of the work of the TQN – Theory of Quantum Nanostructures, and many other groups worldwide, is to model quantum systems using conventional computers to crack down the equations.
It is well established that quantum error correction can improve the performance of quantum sensors. But new theory work cautions that, unexpectedly, the approach can also give rise to inaccurate and misleading results — and shows how to rectify these shortcomings.
Researchers around the world are exploring how the smallest bits of matter and energy, such as atoms, electrons and photons, can relay information by making essential use of their quantum properties. These unique properties are described by a branch of physics called quantum mechanics, which was originally devised to explain phenomena at the atomic and subatomic scales, but is now central to our understanding of all matter. At the U.S. Department of Energy’s (DOE) Argonne National Laboratory, quantum information science (QIS) is a burgeoning discipline that stands to revolutionize computing, science and communication.
FAST Labs to advance quantum technology and revolutionize radio frequency (RF) sensing by breaking constraints to antenna designs that have persisted for more than a century.
Quantum entanglement—or what Albert Einstein once referred to as “spooky action at a distance”— occurs when two quantum particles are connected to each other, even when millions of miles apart. Any observation of one particle affects the other as if they were communicating with each other. When this entanglement involves photons, interesting possibilities emerge, including entangling the photons’ frequencies, the bandwidth of which can be controlled.
The Ulsan National Institute of Science and Technology (UNIST) said in a statement on November 1 that its research team has developed a solid-state quantum structure material using silicon carbide nanowires.
Quantum Information Science and Technology, which includes quantum computing, networking, sensing, and metrology, leverages the fundamental properties of matter to generate new information technologies. For example, quantum computers can, in principle, use the unique properties of atoms and photons to solve certain types of problems exponentially faster than a conventional computer can. Over many decades, harnessing quantum aspects of nature has produced critical technologies.
A quantum communications experiment was launched into low orbit around Earth from the International Space Station (ISS). A collaborative experiment of the University of Illinois Urbana-Champaign and the University of Waterloo, CAPSat (Cool Annealing Payload Satellite) contains single-photon detectors, which can be used as receivers for unhackable quantum communications.
Throughout history, there have been revolutionary technological innovations that have changed the way the world operates and quantum technology is set to be the next of these developments. While quantum computing is regularly discussed in the media, it is largely hogging the limelight – that’s right, the scope of quantum tech is far broader than just increasing computing power beyond anything that is currently available. With some of it very close to the market, it’s quite strange that we don’t hear about all the other elements of quantum technology that are soon going to change our lives.
Wits University announced it has successfully secured R8 million in seed funding from the Department of Science and Innovation (DSI) towards implementing Phase 1 on behalf of the South African Quantum Technology Initiative (SA QuTI).
