Physicists pioneer new quantum sensing platform

Quantum sensors detect the smallest of environmental changes—for example, an atom reacting to a magnetic field. As these sensors "read" the unique behaviors of subatomic particles, they also dramatically improve scientists' ...

Twisting and binding matter waves with photons in a cavity

Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom "recoils" in the opposite direction, making it ...

New work reveals the 'quantumness' of gravity

Gravity is part of our everyday life. Still, the gravitational force remains mysterious: to this day we do not understand whether its ultimate nature is geometrical, as Einstein envisaged, or governed by the laws of quantum ...

Physicists discover new way to make strange metal

By tinkering with a quantum material characterized by atoms arranged in the shape of a sheriff's star, MIT physicists and colleagues have unexpectedly discovered a new way to make a state of matter known as a strange metal. ...

New system boosts efficiency of quantum error correction

The fragile qubits that make up quantum computers offer a powerful computational tool, yet also present a conundrum: How can engineers create practical, workable quantum systems out of bits that are so easily disturbed—and ...

Quantum challenge to be solved one mile underground

Radiation from space is a challenge for quantum computers as their computation time becomes limited by cosmic rays. Researchers from Chalmers University of Technology, Sweden, and University of Waterloo in Canada are now ...

Steering toward quantum simulation at scale

Researchers simulated a key quantum state at one of the largest scales reported, with support from the Quantum Computing User Program, or QCUP, at the Department of Energy's Oak Ridge National Laboratory.

Bounding the amount of entanglement from witness operators

A team of researchers has proposed an approach to quantify entanglement using the standard entanglement witness procedure under three common experimental scenarios. Their work is published in Physical Review Letters.

Springing simulations forward with quantum computing

Though "coupled oscillations" may not sound familiar, they are everywhere in nature. The term "coupled harmonic oscillators" describes interacting systems of masses and springs, but their utility in science and engineering ...
