Researchers build new device that is a foundation for quantum computing
Scientists led by the University of Massachusetts Amherst have adapted a device called a microwave circulator for use in quantum computers, allowing them for the first time to precisely tune the exact degree of nonreciprocity between a qubit, the fundamental unit of quantum computing, and a...
New system boosts efficiency of quantum error correction
The fragile qubits that make up quantum computers offer a powerful computational tool, yet also present a conundrum: How can engineers create practical, workable quantum systems out of bits that are so easily disturbed—and wiped of data—by tiny changes in their environment?
Physicists pioneer new quantum sensing platform
Quantum sensors detect the smallest of environmental changes—for example, an atom reacting to a magnetic field. As these sensors "read" the unique behaviors of subatomic particles, they also dramatically improve scientists' ability to measure and detect changes in our wider environment.
Scientists show that there is indeed an 'entropy' of quantum entanglement
Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lami from the University of Amsterdam have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of entropy for the phenomenon of quantum entanglement.
Generating graph states of atomic ensembles via photon-mediated entanglement
Graph states, a class of entangled quantum states that can be represented by graphs, have been the topic of numerous recent physics studies, due to their intriguing properties. These unique properties could make them particularly promising for quantum computing applications, as well as a wider...
Researchers unlock potential of 2D magnetic devices for future computing
Imagine a future where computers can learn and make decisions in ways that mimic human thinking, but at a speed and efficiency that are orders of magnitude greater than the current capability of computers.
Unveiling a New Quantum Frontier: Frequency-Domain Entanglement
Sydney, Australia (SPX) May 16, 2024 - Scientists have introduced a new form of quantum entanglement known as frequency-domain photon number-path entanglement. This advancement in quantum physics involves a tool called a frequency beam s
