The realization of a single-quantum-dot heat valve

While many research teams worldwide are trying to develop highly performing quantum computers, some are working on tools to control the flow of heat inside of them. Just like conventional computers, in fact, quantum computers ...

Quantum heat engine behaviour observed in a qubit

Although many of today's accepted theories of classical thermodynamics predate even the industrial revolution they helped to propel, many open questions remain around how these ideas translate to the level of single quantum ...

Generating multiphoton quantum states on silicon

In a recent study now published in Light: Science & Applications, Ming Zhang, Lan-Tian Feng and an interdisciplinary team of researchers at the departments of quantum information, quantum physics and modern optical instrumentation ...

Nonlinear integrated quantum electro-optic circuits

Physicists envision that the future of quantum computation networks will contain scalable, monolithic circuits, which include advanced functionalities on a single physical substrate. While substantial progress has already ...

Blind quantum computing for everyone

(Phys.org)—For the first time, physicists have demonstrated that clients who possess only classical computers—and no quantum devices—can outsource computing tasks to quantum servers that perform blind quantum computing. ...
