University of Sydney researchers have designed a new quantum error correction framework that reduces qubit requirements, making way for more efficient quantum computing and compact memory systems.
Atlantic Quantum Corp. announces its selection by AFWERX for a $1.25 million Direct-to-Phase II contract, focusing on fluxonium-based quantum computing hardware. This collaboration, aimed at addressing critical challenges for the Department of the Air Force (DAF), is a part of the streamlined Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) process. Atlantic Quantum’s innovation aims to overcome current quantum hardware limitations related to error rates and scalability.
Quantum computing has a crucial weakness that may severely delay, if not kill outright, its chances of becoming a way of running algorithms that classical computers cannot handle: its susceptibility to noise.
Many applications require quantum processors with millions of quantum bits. Today’s prototypes merely come up with a few of these compute units. At some point, the number of signal lines becomes a bottleneck. The lines take up too much space compared to the size of the tiny qubits. And a quantum chip cannot have millions of inputs and outputs.
The key takeaway from the recent NIST announcement is that the NIST algorithms finally bring clarity and certainty to the business community as they transition from algorithms such as RSA encryption to a new, tangible PQC framework.
To start to do anything useful with quantum computers, we need to reach the million-qubit scale. It’s a monumental task but not an impossible one with the right engineering focus to scale to the million-qubit range.
For 25 years, QEC researchers have largely focused on mathematical strategies for encoding qubits and efficiently detecting errors in the encoded sets. Only recently have investigators begun to address the thorny question of how best to implement the full QEC feedback loop in real hardware…
At Innsbruck, Austria, a team of experimental physicists has now implemented a universal set of computational operations on fault-tolerant quantum bits for the first time, demonstrating how an algorithm can be programmed on a quantum computer so that errors do not spoil the result…
Three research groups demonstrated more than 99 percent fidelity for “if-then” logic gates between two silicon qubits.
French quantum computing startup, Alice&Bob, announced a major advance towards the first marketable quantum computer. In a major scientific breakthrough, Alice&Bob has eliminated one of the main barriers to, and significantly reduced the complexity of, delivering a functional quantum computer – a goal that could now be within reach.
