Quantum phase transitions describe abrupt changes in the ground state of a quantum system at absolute zero when a control parameter is varied. They are distinguished from classical phase transitions ...

Quantum phase transitions and topological phases constitute a vibrant domain within condensed matter physics. Unlike classical transitions driven by thermal fluctuations, quantum phase transitions ...

Physicists working at ultra-low temperatures have stumbled onto a quantum phase that should not exist according to the usual ...

A stable "exceptional fermionic superfluid," a new quantum phase that intrinsically hosts singularities known as exceptional points, has been discovered by researchers at the Institute of Science ...

Researchers report a field-tuned quantum phase transition in a disordered iron-based alloy family, TiFexCu2x−1Sb. Thermodynamic and transport measurements reveal a quantum critical point near 0.13 ...

The city-based Inter-University Centre for Astronomy and Astrophysics (IUCAA) has developed an indigenous technology called ...

A new study, co-led by Rice University’s Qimiao Si, brings these two together and discovered a new quantum state of matter.

Quantum computers can outperform even the best classical supercomputers thanks to quantum entanglement and superposition, but even they can’t solve some problems. A new preprint study shows how ...

The application of quantum phase estimation in MicroAlgo's quantum neural network training not only fully utilizes the parallelism of quantum computing, greatly accelerating the training process of ...
