Quantum entanglement in quasiparticles: A stealth mode against disorder
Physicists at Julius-Maximilians-Universität Würzburg (JMU) have made a discovery that could boost the understanding of the role of entanglement in high-temperature copper oxide superconductors. The low-energy quasiparticles of these enigmatic quan.....»»
Computing how quantum states overlap
Quantum many-body systems are things such as atomic nuclei that consist of many tiny particles moving in complex ways. This makes it extremely difficult to predict how the systems behave as the particles interact. To study these systems, researchers.....»»
Magnetic levitation: New material offers potential for unlocking gravity-free technology
Researchers at the Quantum Machines Unit at the Okinawa Institute of Science and Technology (OIST) are studying levitating materials—substances that can remain suspended in a stable position without any physical contact or mechanical support......»»
Scientists investigate information propagation in interacting bosonic systems
A new study by scientists from Japan explores the propagation of quantum information within interacting boson systems like Bose-Einstein condensates (BECs), revealing the potential for accelerated transmission unlike previously thought......»»
Nonvolatile quantum memory: Discovery points path to flash-like memory for storing qubits
Rice University physicists have discovered a phase-changing quantum material—and a method for finding more like it—that could potentially be used to create flash-like memory capable of storing quantum bits of information, or qubits, even when a q.....»»
Chemical reactions can scramble quantum information as well as black holes
If you were to throw a message in a bottle into a black hole, all of the information in it, down to the quantum level, would become completely scrambled. Because in black holes this scrambling happens as quickly and thoroughly as quantum mechanics al.....»»
Simulating magnetization in a Heisenberg quantum spin chain
The rapid progress of quantum simulators is now enabling them to study problems that before have been limited to the domain of theoretical physics and numerical simulation. A team of researchers at Google Quantum AI and their collaborators showed thi.....»»
"It"s ultimately about predicting everything"—theory could be a map in the hunt for quantum materials
A breakthrough in theoretical physics is an important step toward predicting the behavior of the fundamental matter of which our world is built. It can be used to calculate systems of enormous quantities of quantum particles, a feat thought impossibl.....»»
New focused approach can help untangle messy quantum scrambling problems
The world is a cluttered, noisy place, and the ability to effectively focus is a valuable skill. For example, at a bustling party, the clatter of cutlery, the conversations, the music, the scratching of your shirt tag and almost everything else must.....»»
Quantum error correction used to actually correct errors
