Achieving quantum supremacy

Researchers have made good on their claim to quantum supremacy. Using 53 entangled quantum bits ('qubits'), their Sycamore computer has taken on -- and solved -- a problem considered intractable for classical computers.

Physicists use light waves to enable ultrafast quantum computing

Scientists have discovered that terahertz light - light at trillions of cycles per second - can act as a control knob to accelerate supercurrents. That can help open up the quantum world of matter and energy at atomic and subatomic scales.

Scientists harness quantum computing to view alternative futures

A team of researchers from Singapore and Australia have implemented a prototype quantum device that can generate and analyze a quantum superposition of possible futures.

Reversing the flow of time on a quantum computer

Researchers have developed an algorithm to simulate returning a particle briefly to the past. The results suggest new paths for exploring the backward flow of time in quantum systems.

IBM's quantum computer has reached its 'highest quantum volume to date'

IBM has announced that its System Q One quantum computer has doubled in performance in each of the past two years. IBM is one of the big-name companies working to create a truly useful quantum computer.

IBM Just Unveiled The First Commercial Quantum Computer

IBM unveiled the IBM Q System One, billed as the first-ever quantum computer designed for businesses to put to their own use – though the company is clear that this is only the first step towards a broader revolution.

A new type of quantum computer has smashed every record

IonQ was founded on a gamble that 'trapped ion quantum' computing could outperform the silicon-based quantum computers that Google and others are building. As of right now, it does.

This Could Be the Best Quantum Computer Yet

A startup based in Maryland has released and tested an impressive new quantum computer that demonstrates the power of an occasionally overlooked quantum computing architecture.

One step closer to complex quantum teleportation

Austrian scientists are pursuing the idea to use more complex quantum systems. The developed methods and technologies could in the future enable the teleportation of complex quantum systems.

First proof of quantum computer advantage

Scientists have now demonstrated for the first time that quantum computers do indeed offer advantages - they developed a quantum circuit that can solve a problem that is unsolvable using any equivalent classical circuit.

Quantum Experiment Creates May Be The Most Entangled Controllable Device Yet

A new quantum device entangles 20 quantum bits together at the same time, making it perhaps one of the most entangled, controllable devices yet.

New Silicon Chip-Based Quantum Computer Passes Major Test 

Researchers from two teams now working with Intel have reported advances in a new quantum computing architecture, called spin qubits.

Australian Scientists' Quantum Computing Breakthrough

A team from Australia have found a "quantum hack" - a way to modify qubit surface codes, improving quantum error correction by up to four hundred per cent.

We've Entered a New Era of Quantum Computing

When future computing historians look back on the era starting around 2017, they’ll have a word to describe it: the NISQ era.
