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 ...

In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum ...

A quantum error-correcting code is designed to identify and correct ... to the encoded state before decoding. We therefore calculate logical failure rates Figure 4: Gauge color code logical ...

Quantum computers can one day be vastly more powerful than the most powerful supercomputers on the planet — but only if ...

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 from the University ...

As mentioned above, there are many potential error-correction schemes, with new ones being developed regularly. The team behind the new work calls the scheme a tesseract code, after the four ...

A way to greatly enhance the efficiency of a method for correcting errors in quantum computers has been realized by theoretical physicists at RIKEN. This advance could help to develop larger, more ...

Surface code: illustration of how error correction works for bit and phase flips. The measure qubits on light blue backgrounds check for phase flip errors while the ...

"Knowing the two-qubit gate fidelities, knowing how many interaction zones, how much parallelism you can have, we then optimize our error-correction codes for that," Svore said. The Carbon code ...

Unlike binary bits of information in ordinary computers, “qubits” consist of quantum particles that have some probability of being in each of two states, designated |0 and |1 , at the ...
