The first observation of time-domain oscillations between two distant semiconductor spin qubits
Quantum computing holds the promise of outperforming classical computing on some optimization and data processing tasks. The creation of highly performing large-scale quantum computers, however, relies on the ability to support ...
Quantum phase transition in indium oxide films defies superconductor norms
A team of physicists at Université Grenoble Alpes, CNRS, in France, working with a colleague from Karlsruhe Institute of Technology, in Germany, has observed an odd quantum phase transition in indium oxide films. In their ...
Secret lab developing UK's first quantum clock
A top-secret lab in the UK is developing the country's first quantum clock to help the British military boost intelligence and reconnaissance operations, the defense ministry said Thursday.

A new calculation of the electron's self-energy improves determination of fundamental constants
When quantum electrodynamics, the quantum field theory of electrons and photons, was being developed after World War II, one of the major challenges for theorists was calculating a value for the Lamb shift, the energy of ...
Researchers achieve calculation of Jones polynomial based on the Majorana zero modes
A research team has experimentally calculated the Jones polynomial based on the quantum simulation of braided Majorana zero modes. The research team determined the Jones polynomials of different links through simulating the ...

Advancing unidirectional heat flow: The next era of quantum thermal diodes
Heat management at the nanoscale has long been a cornerstone of advanced technological applications, ranging from high-performance electronics to quantum computing. Addressing this critical challenge, we have been deeply ...
Numerical simulations show how the classical world might emerge from the many-worlds universes of quantum mechanics
Students learning quantum mechanics are taught the Schrodinger equation and how to solve it to obtain a wave function. But a crucial step is skipped because it has puzzled scientists since the earliest days—how does the ...
Low-frequency photonic simulator breaks barriers
A research team led by Prof. Li Chuanfeng from the University of Science and Technology of China (USTC) has achieved a breakthrough in quantum photonics. They developed an on-chip photonic simulator capable of simulating ...

Quantum research sheds new light on how cells communicate
Have you ever thought that light might hold a key to life's mysteries? One hundred years ago, Alexander Gurwitsch dared to propose that living cells emit faint ultraviolet light, invisible to the naked eye, to communicate ...
Can entangled particles communicate faster than light?
Entanglement is perhaps one of the most confusing aspects of quantum mechanics. On its surface, entanglement allows particles to communicate over vast distances instantly, apparently violating the speed of light. But while ...
