Quantum computing researchers develop an 8-photon qubit chip

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 integrated-circuit chip. With this system, they can explore various quantum phenomena, such as multipartite entanglement resulting from the interaction of the photons.Quantum Physics NewsRead More

Scientists find a new way of entangling light and sound

For a wide variety of emerging quantum technologies, such as secure quantum communications and quantum computing, quantum entanglement is a prerequisite. Scientists at the Max-Planck-Institute for the Science of Light (MPL) have now demonstrated a particularly efficient way in which photons can be entangled with acoustic phonons.Quantum Physics NewsRead More

How ‘clean’ does a quantum computing test facility need to be?

Now is the time to banish low-level radioactive energy sources from facilities that house and conduct experiments with superconducting qubits, according to a pair of recently published studies. Significantly improving quantum device coherence times is a key step toward an era of practical quantum computing.Quantum Physics NewsRead More
