atomically precise manufacturingPath to Million Qubit Quantum Computers Using Atoms and Lasers

Atom Computing is building quantum computers using individually controlled atoms. As one of the world’s leading researchers in atomic clocks and neutral atoms, Benjamin Bloom (co-founder of Atom Computing) built the world’s fastest atomic clock, and it is considered the …

physicsHoneywell Trapped Ion Quantum Computer

Honeywell Quantum Solutions has demonstrated record-breaking high fidelity quantum operations on their trapped-ion qubits. It is a major step towards producing the world’s most powerful quantum computer. Honeywell targets an operational trapped ion quantum computer by the end of 2019. …

diamondsQuantum Control in Nanodiamonds

Quantum coherence control usually requires low temperature environments. Even for nitrogen-vacancy center spins in diamond, a remarkable exception, the coherence signal is limited to about 700 K due to the quench of the spin-dependent fluorescence at a higher temperature. Here …

physicsMagnetoresistance in a magnetic nodal semimetal

Transport coefficients of correlated electron systems are often useful for mapping hidden phases with distinct symmetries. Researchers report a transport signature of spontaneous symmetry breaking in the magnetic Weyl semimetal CeAlGe system in the form of singular angular magnetoresistance (SAMR). …

energyClarifying What Commonwealth Fusion Systems Will Do

Steven B. Krivit points out that Commonwealth Fusion Systems will not get to true energy breakeven in 2025. The plans for the SPARC reactor specify a fusion power output of 50 to 100 MW of heat. Thermal power to heat …

physicsWhat Quantum Supremacy Should Look Like if Google’s Neven if Correct

The current state of noisy qubit quantum computers is a bit difficult to assess. Superconducting quantum chips and ion trapped quantum computers are in the 16 qubit to 100 qubit range. Rigetti Computing is seeking an application that will give …

energyNew Mode Enables Four-Fold Increase in Tokamak Fusion Performance

Super-H Mode allows tokamaks to achieve higher fusion performance than previously possible. In recent experiments operating in and near the Super H-mode regime, researchers have achieved record-breaking values of fusion gain for a device of DIII-D’s size. Fusion gain is …

energyFirst Light fusion Using Hypervelocity Projectiles for Pulsed Fusion

Startup First Light Fusion (FLF) claims it is on target to achieve fusion gain (more energy out than goes in) by 2024. They are not using lasers or intense magnetic fields which can prove to be very complicated and costly …

magnetsPressure Changes Magnetism and Can Improve Electronic Device Performance

Oak Ridge researchers used pressure to manipulate magnetism in thin film materials used to enhance performance in electronic devices. They used neutron scattering at Oak Ridge National Laboratory’s Spallation Neutron Source to explore the spacial density of atoms and observe …

futureQuantum Sensing With Squeezed State of Light Reduces Noise

Oak Ridge National Labs (ORNL) has quantum sensors that use a “squeezed” state of light to greatly reduce statistical noise that occurs in ordinary light. This could impact a wide range of potential applications from airport security scanning to gravitational …
