In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space ...

For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...

Two quantum information theorists have solved a decades-old problem that will free up quantum computing power. University of Sydney quantum researchers Dominic Williamson and Nouédyn Baspin have ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

In recent years, quantum computers have begun to handle double-digit quantum bits, or qubits. However, many essential applications targeted by quantum computers, such as quantum chemistry, ...

Researchers at the University of New South Wales (UNSW) have used the famous Schrödinger’s cat thought experiment in the real world to find better ways of correcting errors that accumulate during ...

Nov. 10, 2024 — The University of Sydney has announced that quantum researchers Dominic Williamson and Nouédyn Baspin have developed what the university called “a transformative new architecture for ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...

Quantum error correction (QEC) and fault-tolerant computation provide the critical framework for realising reliable quantum processors in the presence of inevitable ...

That’s why the field is racing to develop and implement quantum error-correction (QEC) schemes to alleviate the technology’s inherent unreliability. These approaches involve building redundancies into ...

Quantum is smart. The progression toward embryonic quantum computing services represents a shift (you know what kind) in terms of the amount of intelligence we can apply to computing, data analytics ...
