TIME CRYSTALS IN THE LIMELIGHT | UC Berkeley physicist Norman Yao first described five years ago how to make a time crystal — a new form of matter whose patterns repeat in time instead of space. Unlike crystals of emerald or ruby, however, those time crystals existed for only a fraction of a second.  Source: Physics BERKELEY.   TIME CRYSTALS IN THE LIMELIGHT…

Multiport based teleportation – transmission of a large amount of quantum information | We analyse the problem of transmitting a number of unknown quantum states or one composite system in one go. We derive a lower bound on the performance of such process, measured in the entanglement fidelity. The obtained bound is effectively computable and outperforms the explicit values of the entanglement fidelity calculated for the pre-existing variants of the port-based protocols, allowing for teleportation of a much larger amount of quantum information. The comparison with the exact formulas and similar analysis for the probabilistic scheme is also discussed. In particular, we present the closed-form expressions for the entanglement fidelity and for the probability of success in the probabilistic scheme in the qubit case in the picture of the spin angular momentum.  Source: Quantum Journal.   Multiport based teleportation – transmission of a large amount of quantum information…

Key Witness Helps Scientists Detect ‘Spooky’ Quantum Entanglement in Solid Materials | Quantum entanglement occurs when two particles appear to communicate without a physical connection, a phenomenon Albert Einstein famously called “spooky action at a distance.” Nearly 90 years later, a team led by the U.S. Department of Energy’s Oak Ridge National Laboratory demonstrated the viability of a “quantum entanglement witness” capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material.  Source: HPC wire.   Key Witness Helps Scientists Detect ‘Spooky’ Quantum Entanglement in Solid Materials…

How a novel radio frequency control system enhances quantum computers | A team of physicists and engineers at Lawrence Berkeley National Laboratory (Berkeley Lab) successfully demonstrated the feasibility of low-cost and high-performance radio frequency modules for qubit controls at room temperature. They built a series of compact radio frequency (RF) modules that mix signals to improve the reliability of control systems for superconducting quantum processors. Their tests proved that using modular design methods reduces the cost and size of traditional RF control systems while still delivering superior or comparable performance levels to those commercially available.  Source: PHYS.ORG.   How a novel radio frequency control system enhances quantum computers…
