Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Using single photons as qubits has become a prominent strategy in quantum information technology. Accurately determining the number of photons is crucial in various quantum systems, including quantum ...

This close-up photograph shows an exquisitely sensitive single Performance-Enhanced Array for Counting Optical Quanta (PEACOQ) detector, which is being developed at JPL to detect single photons – ...

Single photons in the mid-infrared can reveal faint galaxies or carry fragile quantum signals across space. They are valuable in astronomy, quantum communication, and even medical imaging. But ...

The technology of integrated photonic quantum chips has successfully enabled the on-chip preparation, manipulation, and detection of photonic quantum states, thereby significantly accelerating the ...

Data security on the internet is under threat: in the future, quantum computers could decode even encrypted files sent over the internet in no time. Researchers worldwide are, therefore, experimenting ...

Quantum entanglement has shifted from a philosophical puzzle to a design brief for engineers working at the scale of atoms, ...

A group of South Korean researchers has successfully developed an integrated quantum circuit chip using photons (light particles). It is a system capable of controlling eight photons using a photonic ...

You are watching a long-standing assumption in physics and engineering quietly fall apart. Researchers at Northwestern ...

One notable type is the superconducting nanowire single-photon detector (SNSPD). SNSPDs utilize ultra-thin superconducting wires that quickly transition from a superconducting state to a resistive ...
