Recent work has constructed a relation problem that a noisy constant-depth quantum circuit (QNC0) can solve with near certainty (probability 1−o(1)), but that any bounded fan-in constant-depth classical circuit (NC0) fails with some constant probability. It
For years, physicists have been looking for materials that emulate a Kitaev honeycomb (solid-state model known to birth Majorana fermions in magnetic fields). Physicists from Chung-Ang University, Korea, unveiled the existence of Majorana fermions in α-RuCl3,
A team of researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) used a quantum computer to successfully simulate an aspect of particle collisions that is typically neglected in high-energy physics experiments, such as those that
To build a universal quantum computer from fragile quantum components, effective implementation of Quantum Error Correction (QEC) is an essential requirement and a central challenge. Since qubits are intrinsically fragile, the most outstanding challenge of
A collaboration between the Universities of Hong-Kong, Grenoble and Vienna, as well as the Austrian Academy of Sciences has revealed novel techniques to reduce noise in quantum communication. The primary approach to overcome these noise
Fault-tolerant quantum computers offer the promise of dramatically improving machine learning through speed-ups in computation or improved model scalability. In the near-term, however, the benefits of Quantum Machine Learning (QML) are not so clear. Understanding
NEC Corporation and ParityQC have announced that they have started collaborating in the field of Quantum Annealing. NEC will be the first company worldwide implementing the ParityQC architecture for quantum annealing devices. The collaboration entails
An international team of researchers led by the University of Surrey has proven the existence of the fabled multi-photon Fano effect in an experiment. Ionization is when electrons absorb photons to gain enough energy to
Researchers from the University of Oxford and the Université libre de Bruxelles have developed a theory of causality in quantum theory, according to which cause-effect relations can sometimes form cycles. This theory offers a novel
Researchers at Heidelberg University‘s Physics Institute have recently observed the Pauli principle directly in a continuous system comprised of up to six particles. Their experiment could pave the way towards a better understanding of strongly
