New quantum sensing method measures three light properties at once with high precision

A new method for measuring three different properties of light, at the same time, has been developed using an interferometry-based quantum sensing scheme capable of simultaneously estimating multiple parameters of an optical network.

The approach could help advances in the fields of medicine and astronomy, for example, to improve the precision and scope of quantum measurements across applications ranging from biological imaging to gravitational wave detection.

To date, it has only been possible to measure each parameter individually. However, research published in The European Physical Journal Plus has demonstrated, for the first time, that three independent optical parameters can be measured in a single “view” with ultimate quantum precision, without the need to examine each one of them individually.

Quantum Route Redirect PhaaS targets Microsoft 365 users worldwide

A new phishing automation platform named Quantum Route Redirect is using around 1,000 domains to steal Microsoft 365 users’ credentials.

The kit comes pre-configured with phishing domains to allow less skilled threat actors to achieve maximum results with the least effort.

Since August, analysts at security awareness company KnowBe4 have noticed Quantum Route Redirect (QRR) attacks in the wild across a wide geography, although nearly three-quarters are located in the U.S.

Nobel winner, HPE and chip industry firms team up to make a practical quantum supercomputer

John M. Martinis, one of this year’s winners of the Nobel Prize in physics for breakthroughs in quantum computing, on Monday formed an alliance with HPE and several chip firms to create a practical, mass-producible quantum supercomputer.

Physicists Discover Bizarre “Quantum Pinball” State of Matter

Physicists have discovered how to make electrons “freeze” and “melt” into bizarre quantum patterns, forming a new kind of matter where solid and liquid coexist. Electricity drives nearly every aspect of modern life, from powering vehicles and smartphones to running computers and countless other d

Quantum entanglement distribution via uplink satellite channels

Significant work has been done to develop quantum satellites, which generate entangled pairs in space and distribute them to ground stations separated some distance away. The reverse “ uplink’’ case, where pairs are generated on the ground and swapped on the satellite using an optical Bell measurement, has not been seriously considered due to a prevailing assumption that it is practically infeasible. In this paper, we illustrate the feasibility of performing Discrete Variable photonic Bell measurements in space by conducting a detailed numerical analysis to estimate the channel efficiency and attainable pair fidelity for various satellite-station configurations. Our model accounts for a wide range of physical effects such as atmospheric effects, stray photons, and mode mismatch.

Physicists Take the Imaginary Numbers Out of Quantum Mechanics

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth with accurate calculations of hydrogen’s emission and absorption of light. There was, however, a snag. The central equation of quantum mechanics featured the imaginary number i, the square root of −1.

Physicists knew i was a mathematical fiction. Real physical quantities like mass and momentum never yield a negative amount when squared. Yet this unreal number that behaves as i2 = −1 seemed to sit at the heart of the quantum world.

After deriving the i-riddled equation — essentially the law of motion for quantum entities — Erwin Schrödinger expressed the hope that it would be replaced by an entirely real version. (“There is undoubtedly a certain crudeness at the moment” in the equation’s form, he wrote in 1926.) Schrödinger’s distaste notwithstanding, i stuck around, and new generations of physicists took up his equation without much concern.
