A filter for cleaner qubits

A research team at the Tokyo Medical and Dental University (TMDU), RIKEN, and the University of Tokyo have demonstrated how to increase the lifetime of qubits inside quantum computers by using an additional "filter" qubit. ...

Quantum interference in the service of information technology

Scientists from the Faculty of Physics, University of Warsaw, in collaboration with the University of Oxford and NIST, have shown that quantum interference enables processing of large sets of data faster and more accurately ...

First demonstration of antimatter wave interferometry

Matter waves constitute a crucial feature of quantum mechanics, in which particles have wave properties in addition to particle characteristics. This wave-particle duality was postulated in 1924 by the French physicist Louis ...

Quasiparticles experimentally shown to interfere for first time

Qubits, the units used to encode information in quantum computing, are not all created equal. Some researchers believe that topological qubits, which are tougher and less susceptible to environmental noise than other kinds, ...

Quantum strangeness gives rise to new electronics

Noting the startling advances in semiconductor technology, Intel co-founder Gordon Moore proposed that the number of transistors on a chip will double each year, an observation that has been born out since he made the claim ...
