Light not only plays a key role as an information carrier for optical computer chips, but also in particular for the next generation of quantum computers. Its lossless guidance around sharp corners on tiny chips […]
Physicists have developed a theory describing how space reflection and time reversal symmetries can be exploited, allowing for greater control of transport and correlations within quantum materials. Click to rate this post! [Total: 0 Average: […]
Quantum technology — and their ability to affect global security — was specifically called out during the first public speech of the chief of the UK Secret Intelligence Service (MI6). He also said that the […]
Quantum computers, enthusiasts forecast, will one day work no end of miracles — from breaking digital encryptions to designing wonder drugs. At this early stage, however, the advantage of many quantum algorithms remains speculative. And […]
In 1973, physicist Philip W. Anderson theorized the existence of a new state of matter that has been a major focus of the field, especially in the race for quantum computers. Click to rate this […]
Superconducting coupling between two regions separated by a one micron wide ferromagnetic compound has been proved by an international team. This macroscopic quantum effect, known as Josephson effect, generates an electrical current within the ferromagnetic […]
Quantum 5, 596 (2021). https://doi.org/10.22331/q-2021-12-02-596 Variational quantum eigensolvers (VQEs) are a promising class of quantum algorithms for preparing approximate ground states in near-term quantum devices. Minimizing the error in such an approximation requires designing ansatzes […]
Quantum 5, 595 (2021). https://doi.org/10.22331/q-2021-12-02-595 In order to build a large scale quantum computer, one must be able to correct errors extremely fast. We design a fast decoding algorithm for topological codes to correct for […]
Quantum computer and many other quantum technologies rely on the generation of quantum-entangled pairs of electrons. However, the systems developed so far typically produce a noisy and random flow of entangled electrons, which hinders synchronized […]
UNIVERSITY RESEARCH NEWS — Today’s quantum computers are complicated to build, difficult to scale up, and require temperatures colder than interstellar space to operate. These challenges have led researchers to explore the possibility of building […]
