(NHK-World.Japan) Scientists in Japan have been using a powerful computer to work out ways to cut congestion at places such as shopping malls in the face of the coronavirus. A trial calculation using a quantum computer found the density of crowds at peak periods in commercial facilities can be reduced by 49 to 56 percent…..

(OSA.org) Researchers have used a technology borrowed from quantum optics to perform optical coherence tomography (OCT) with much lower light powers than previously possible. Optical coherence tomography (OCT) is used in medical diagnostics. Researchers in New Zealand and Poland have demonstrated OCT imaging that requires a tiny fraction of the light power of existing systems…..

(NewDelhiTimes) Quantum computing has presented challenges. The first such challenge discussed in this article pertains to cybersecurity. There are two major sets of challenges that require collective action by the global community. First, quantum computing has the potential, if used maliciously, to break the systemically important cryptographic underpinnings of the infrastructure on which enterprises and…..

(InsideUCRiverside) wireless communications are essential. But due to the open nature of wireless transmissions, information security is a unique issue of challenge. The widely deployed methods for information security are based on digital encryption, which in turn requires two or more legitimate parties to share a secret key. The conventional solution to this challenge is…..

(Medium.com) In this, the first of a promised series of articles, the authors discuss “Quantum Sensing of Magnetic Fields.” Magnetic field is often the easiest thing for a quantum system to measure. The most common one for quantum sensors is the familiar Zeeman effect, where magnetic field causes one energy level of the quantum system…..

(ScienceAlert) A small CubeSat satellite orbiting earth, appropriately called SpooQy-1, was used to produce pairs of entangled photons using a blue laser diode and non-linear crystals. The achievement is impressive on a number of levels: not only did it happen in actual space, it was done on a piece of equipment less than 20 cm…..

(Phys.org) Proving quantum supremacy requires at least 50 qubits. For quantum computers working with light, it is equally necessary to have at least 50 photons. And what’s more, these photons have to be perfect, or else they will worsen their own quantum capabilities. There is one important condition: the photons have to be perfect in…..
