Where Will Practical Room Temperature Superconductors Matter?

There have been reports that South Korean researchers have made a practical regular atmospheric pressure room temperature superconductor using basic lab equipment. This would mean superconducting wires and magnets that would not need special cooling. Depending upon your application you might still want to cool the system but you could use regular refrigerants. NOTE: The …

High fidelity Two-qubit Gates on Fluxoniums Using a Tunable Coupler

Superconducting fluxonium qubits provide a promising alternative to transmons on the path toward large-scale superconductor-based quantum computing due to their better coherence and larger anharmonicity. A major challenge for multi-qubit fluxonium devices is the experimental demonstration of a scalable crosstalk-free multi-qubit architecture with high-fidelity single-qubit and two-qubit gates, single-shot readout, and state initialization. Researchers present …

Better Superconducting Arrays to Detect Smaller Nomadic Worlds

NASA’s future telescopes need robust, high-sensitivity, kilopixel-format superconducting arrays that operate over the entire far-IR spectrum. Previously, some of the key technologies needed for these arrays were demonstrated on the High-resolution Airborne Wideband Camera (HAWC+) on the Stratospheric Observatory for Far-Infrared Astronomy (SOFIA). Those detectors provided excellent performance for suborbital far-IR applications, but their production …

New Charge Quantum Interference Device developed

An international collaboration, including researchers from the National Physical Laboratory (NPL) and Royal Holloway, University of London, has successfully demonstrated a quantum coherent effect in a new quantum device made out of continuous superconducting wire – the Charge Quantum Interference Device (CQUID). This research represents an important milestone towards the demonstration of a robust new …

Superconducting Synapse many times faster than human synapses could enable faster artificial brains

Researchers at the National Institute of Standards and Technology (NIST) have built a superconducting switch that “learns” like a biological system and could connect processors and store memories in future computers operating like the human brain. Above – Illustrations showing the basic operation of NIST’s artificial synapse, which could connect processors and store memories in …

Researchers find lost continent Mauritia part of break of ancient 200 million year old Gondwana super-continent

Lava-covered piece of continent is an ancient remnant, left over from the break-up of the supercontinent, Gondwana, which started about 200 million years ago. Scientists have confirmed the existence of a “lost continent” under the Indian Ocean island of Mauritius that was left-over by the break-up of the supercontinent, Gondwana, which started about 200 million …

Switzerland votes to keep nuclear power which provides 35% of electricity

Switzerland has voted to keep their nuclear reactors. Five nuclear reactors provide over one-third of Switzerland’s electricity. Nuclear power is Switzerland’s second largest source of electricity, providing about 35% of electricity in 2015 and complementing 52% hydro to give the country one of the cleanest and most secure electricity systems in the world. Now Swiss …
