Quantum-computing stocks have surged in recent months, reflecting hype that’s at odds with the current financial reality of these businesses, which still bring in minimal revenue. The stocks ...

Quantum Computing stock has surged amid the quantum computing hype but faces skepticism due to its track record. Quantum computing offers immense potential in AI and drug discovery, with market ...

Quantum computing engineers have historically struggled with errors. Building chips with more qubits has led to correspondingly large increases in the number of errors. But Google says Willow does ...

Credit: Sampson Wilcox/Research Laboratory of Electronics MIT researchers have pushed the boundaries of quantum computing by developing fluxonium qubits that demonstrate world-record gate fidelities.

They consider quantum spin ladder models which simulate the system-bath coupling, and focus on the scenarios of gaplessness and degenerate ground states. The numerical results agree very well with ...

One of my favorite anecdotes about prime numbers concerns Alexander Grothendieck, who was among the most brilliant mathematicians of the 20th century. According to one account, he was once asked ...

Physicists have long-suspected that the building blocks of protons experienced quantum entanglement. Now, researchers have the first direct evidence — after using a trick to infer subatomic ...

The team used timed pulses and a form of synthetic light to reduce errors and improve the accuracy of their quantum computer.

Negative comments on the future of quantum computing from Nvidia and Meta CEOs tanked the quantum computing market last week. Today, some positive feedback from Microsoft is getting quantum ...

Quantum computing stocks are crashing following a big rally late last year. Quantum computing is a promising technology but may be decades away from reaching maturity. IonQ and D-Wave take ...

Google’s Willow quantum chip and its ability to significantly reduce the number of errors as it scales up the number of qubits are the newest source of generating fear, uncertainty and doubt ...

Moreover, the greater the number of qubits, which are necessary for Shor’s algorithm, the greater the decoherence. Yet, although these may appear to be intractable problems inherent with quantum ...
