3 weeks agoA 100-year-old theory might explain what's wrong with quantum mechanics
Pilot wave theory, developed by Louis de Broglie a century ago, potentially resolves quantum mechanics' paradoxes by describing particles guided by attendant waves rather than existing in superposition.

3 weeks agoPlease drive carefully: scientists plan to transport volatile antimatter for first time
A core question we want to understand is where did matter come from. And then, if you know about antimatter, it's natural to ask, why is that not here? The process is not understood and we are hunting for clues as to why it happened, says Dr Christian Smorra, a physicist on the Baryon Antibaryon Symmetry Experiment (Base) at Cern.

The Quantum Four—IonQ, D-Wave, Rigetti, and Quantum Computing Inc.—experienced significant stock price gains over two consecutive trading days, reversing earlier year-to-date declines of 15-25%.

NIST has developed a chip that reliably emits a single photon on demand. This ability will improve the efficiency of QKD (quantum key distribution) as we prepare for the arrival of quantum computers. Quantum computers will upend current cryptology by using Shor's algorithm to rapidly negate the current public/private key secure encryption methods. This has largely been solved by NIST's post quantum cryptology (PQC) algorithms.

We demonstrate how the apparent magnetic field induced lattice and CDW intensity change can be explained as a consequence of two independent experimental artifacts: a reconfiguration of atoms at the STM tip apex that alters the amplitudes of CDW modulations, and piezo creep, hysteresis and thermal drift, which artificially distort STM topographs.

A grand aspiration of cavity quantum materials research is to uncover fundamentally new routes for controlling properties of matter by judiciously tailoring the quantum electromagnetic environment. Experiments with dark cavities revealed modified transport properties in the integer and fractional quantum Hall states of a 2D electron gas, as well as cavity-assisted thermal control of the metal-to-insulator transition in charge-density-wave systems.

Analogue quantum simulations are a useful tool for investigating these systems, particularly in regimes in which the applicability of numerical techniques is limited. For different simulator platforms, figures of merit include the electron bandwidth and interaction strength, temperature and the number of simulated lattice sites. Their use is further underscored by the ability to realize distinct lattice geometries, on-site degrees of freedom and by the physical observables that are accessible to experimental measurement.
