For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art ...

Researchers in the US have developed a new technique that could allow quantum computers ...

Quantum technologies relying on entangled photon pairs, such as secure communication networks, quantum LiDAR, and advanced sensing systems, could benefit from the compact, highly efficient photon-pair ...

Researchers developed a simple new technique to enhance nonlinear optical properties, and the potential to create entangled photons, without sacrificing size. Now, in a paper published in Nature ...

Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

In January, a team led by Jim Schuck, professor of mechanical engineering at Columbia Engineering, developed a method for creating entangled photon pairs, a critical component of emerging quantum ...

A new kind of mirror is emerging from quantum physics labs, one that exists not as a chunk of polished glass but as a nanoscale film that can be switched between reflecting and transparent states.

Federal experts working in quantum information sciences and technology mapped out commercialization paths for quantum ...
