A team at Nihon University has figured out how to read entangled quantum states across an entire many-body system without ...

Quantum state estimation lies at the heart of quantum science, providing the means to characterise and verify quantum devices, protocols and materials. At its core is the task of reconstructing the ...

Why does the universe contain matter and (virtually) no antimatter? Scientists have achieved an experimental breakthrough in this context. It can contribute to measuring the mass and magnetic moment ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

Scientists have explored how quantum squeezing can improve measurement precision in complex quantum systems, with potential applications in quantum sensing, imaging, and radar technologies. These ...

One of the biggest challenges in quantum technology and quantum sensing is "noise"–seemingly random environmental disturbances that can disrupt the delicate quantum states of qubits, the fundamental ...

Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small ...

Even though the world is focused on the next development in quantum computing, it ...

A chance meeting during a dip in the ocean was the first step on the road to quantum information science.
