An international research group led by the University of Bristol has made an important advance towards a quantum computer by shrinking down key components and integrating them onto a silicon microchip.
Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions by leaking judiciously chosen information to the environment.
Reliable quantum computing would make it possible to solve certain types of extremely complex technological problems millions of times faster than today’s most powerful supercomputers. Other types of problems that quantum computing could tackle would not even be feasible with today’s fastest machines. The key word is “reliable.”
Researchers at the University of Sydney and Dartmouth College have developed a new way to design quantum memory, bringing quantum computers a step closer to reality. The results will appear June 19 in the journal Nature Communications.
The unique features of the quantum world promises a dramatic acceleration of information processing compared to the fastest class of classical machines.
Researchers at Los Alamos National Labs have been running a quantum internet for the last two and a half years, according to Technology Review.
Quantum computing is controlled by the laws of quantum physics. Nevertheless, such technology offers the potential to perform complicated calculations, or search large amounts of data, at a speed that exceeds by far those that today’s fastest supercomputers are capable of.
Carbon nanotubes can be used as quantum bits for quantum computers. Indeed, a recent study by physicists at the Technische Universitaet Muenchen (TUM) proves the tubes are capable of storing information in the form of vibrations.
An international research group has for the first time demonstrated a quantum algorithm that performs a true calculation, without needing to know the answer before the start.
Princeton researchers have developed a new method that may allow the quick and reliable transfer of quantum information throughout a computing device.
Scientists have taken a big step towards practical quantum computing, with the creation of qubits that can exist in a solid-state system at room temperature.
The realm of quantum physics has always promised faster and more powerful computers. However, quantum versions of basic logic functions are still needed to make the technology a reality.
Big Blue has announced "major advances" in quantum computing device performance that could ultimately help accelerate the design of a practical, full-scale quantum system.
Quantum computing techniques could be used to bring complete security to the cloud, says an international team of scientists.
NIST physicists have for the first time linked the quantum properties of two separated ions by manipulating them with microwaves instead of the usual laser beams.
Innsbruck physicists have set a world record, achieving controlled entanglement of 14 quantum bits (qubits) and thus creating the largest quantum register ever.
An international team of scientists has overcome an obstacle that traditionally interfered with the engineering of quantum systems.
