An international research team from Innsbruck and Geneva has, for the first time, probed the dimensional crossover for ultracold quantum matter. In the regime between one and two dimensions, the quantum particles perceive their world as being 1D or 2D depending on the length scale on which they are probed: For short distances, their world is 1D, but it is 2D for long distances.

A NEW study of quantum mechanics has argued that a real-life multiverse could be much bigger than ever previously imagined.

Just like the fictional multiverse depicted in sci-fi movies and the Marvel superhero universe, we too could be living in a world where multiple realities are possible.

That’s according to a study published on the academic site Arxiv.

The technology can also be used to devise a range of advanced sensors for everyday use and to advance science. Twamley’s lab uses levitating materials to build oscillators, which can be used to develop ultra-sensitive sensors. Making these oscillators work without using external energy sources can make them easier to deploy, and this is what the research team at OIST set out to do. What they faced was a series of challenges.

The device that OIST researchers aimed for was a ‘frictionless’ platform. However, the system would lose energy over time without an external power source. This is known as ‘eddy damping’ since external forces make an oscillating system lose energy.

The other hurdle to overcome would be minimizing the system’s kinetic energy. This is necessary since it can help improve the system’s sensitivity if it were to be used as a sensor. If the kinetic motion can be further cooled to the quantum realm, it could also open up possibilities of more precision measurements.

Nothing makes a mess of quantum physics quite like those space-warping, matter-gulping abominations known as black holes. If you want to turn Schrodinger’s eggs into an information omelet, just find an event horizon and let ‘em drop.

According to theoretical physicists and chemists from Rice University and the University of Illinois Urbana-Champaign in the US, basic chemistry is capable of scrambling quantum information almost as effectively.

The team used a mathematical tool developed more than half a century ago to bridge a gap between known semiclassical physics and quantum effects in superconductivity. They found the delicate quantum states of reacting particles become scrambled with surprising speed and efficiency that comes close to matching the might of a black hole.

Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering.

A research team consisting of Professor Kyoung-Duck Park and Hyeongwoo Lee, an integrated PhD student, from the Department of Physics at Pohang University of Science and Technology (POSTECH) has pioneered an innovative technique in ultra-high-resolution spectroscopy. Their breakthrough marks the world’s first instance of electrically controlling polaritons – hybridized light-matter particles – at room temperature.

This research has been published in Physical Review Letters (“Electrically Tunable Single Polaritonic Quantum Dot at Room Temperature”).

An international research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state—an exotic quantum phenomenon that could help researchers advance quantum computing and energy-efficient electronics.

New technique measures the gravitational pull on a micron-scale levitating magnetic particle.

A national security expert predicts practical quantum computing tools are just three to five years away from integration into the workforce, NextGov is reporting.

Neal Ziring, the Technical Director of the National Security Agency’s (NSA) Cybersecurity Directorate, made the forecast during a recent public sector cybersecurity event hosted by Palo Alto Networks in Palo Alto. As reported by NextGov, Ziring expects the devices to be accessible predominantly through cloud-based platforms.

Ziring added that the impracticality and cost-prohibitive nature of would put on-premise installations for quantum computing systems out of reach for most organizations, including government agencies.
