The innovative wiring architecture allows for bigger and better Quantum Computers

Wiring an innovative way to expand Quantum Computing Last year. Google created the 53-qubit quantum computer, which could do a specific computation much more quickly than the world's most powerful supercomputer. Like the vast majority of today's quantum computing systems, this one includes a tenth of qubits -- quantum counterparts to bits that encode data in traditional computers. To create larger and more efficient devices, today's prototypes must overcome the difficulties of ...

MIT is a major step towards fully realizing Quantum Computation

A tunable coupler can toggle the qubit-qubit interactions on and off. The unwanted or unneeded (ZZ) interactions between two qubits are removed using higher energy levels in the coupler. Credit: Krantz Nanoart MIT researchers have discovered a method to reduce the errors of two-qubit gates dramatically. It is an important improvement towards fully realizing quantum computation. MIT Researchers have created significant progress on the path to quantum computation's fullest realization by demonstrating ...

More powerful batteries are now possible thanks to MIT’s new electrode design.

The new lithium metal anode might create batteries that have more power per kilogram and last longer. An MIT team has devised a lithium metal anode that can increase the lifespan and energy efficiency of the upcoming batteries. New research carried out by engineers from MIT, and other institutions could result in batteries that pack greater power for each pound and last for longer in line with the long-sought purpose to use ...

Scientists create ‘nano chains’ to increase Lithium-Ion Battery Capacity

Artistic illustration of a coin cell with an electrode of copper (left) with a black nanochain structure that scientists have discovered could boost the battery's capacity and speed up charging. Source: Purdue University illustration/Henry Hamann How the battery of your computer or phone lasts depends on the number of lithium ions contained in the battery's negative electrode. If the battery is depleted of the ions, it won't create an electrical current ...

Ultrasound Device Enhances Lithium Battery capacity and charges time

The device is constructed of smart phone components that are available off the shelf that produce sound waves with extremely high frequencies ranging between 100 million and 10 billion hertz. In smartphones, the devices are used mostly to block the wireless cellular signal and recognize and filter voice calls and data. Researchers employed them to produce a flow within the electrolyte of the battery. Image: David Baillot/University California San Diego's Invention ...

NASA Lucy Trojan Asteroid Mission Update: focusing on the Path Forward for the Solar array

NASA's Lucy spacecraft is deploying its solar arrays. Credit NASA's Goddard Space Flight Center NASA plans to run additional testing on the ground using an engineer's model for Lucy's Lucy solar array's motor and lanyard ahead of possibly attempting to deploy fully one of the solar arrays on the probe. A team from the project completed an evaluation on the 1st of December of the solar array problem that did not seem ...

Experiments prove Quantum Computers are more efficient than the sum of their parts

Chip with an ion trap, which researchers utilize to control and capture quantum qubits made of ion (quantum bits). Credit Kai Hudek/JQI Quantum computer research at UMD proves that combining quantum computer parts doesn't involve combining their error rate. Pobody's nerfect isn't just the indifferent bits that calculate the core of computers. However, JQI Christopher Monroe's team and his colleagues at Duke University have made advancements towards ensuring that you can trust ...

Innovative technology may dramatically lower the costs of Electron Sources – for Night Vision Particle Accelerators, Particle Accelerators, and more.

Artist's representation of a halide perovskite-based photocathode. Researchers from Rice University and Los Alamos National Laboratory discovered that halide-perovskite semiconductors (silver) coated by a thin layer of Cesium (blue-green) can be modified to release liberated electrons (gray) across both the ultraviolet and visible spectrum (colored the arrows) and that a new layer of Cesium could be used to regenerate damaged photocathodes.
