A new scheme for cooling a mechanical oscillator in a cavity may allow the observation of quantum effects on macroscopic objects and the realization of ultrasensitive gravitational-wave detectors.
The spin on a silicon defect in diamond can be prepared in a coherent quantum state, a promising sign that it could encode information in a quantum internet.
Qubits based on trapped ions can be prepared and manipulated with record-breaking accuracy, offering a promising scalable platform for quantum computing.
Researchers characterize a single-photon source, proving it emits nonclassical states of light that may be useful for quantum communication schemes.
An experimental demonstration of a novel quantum analysis tool will allow diagnosis of entanglement in a much broader set of states.
A secure communication channel that relies on quantum entanglement survives despite the noisy break up of the entanglement itself.
