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 ...

"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

Get the latest federal technology news delivered to your inbox. In its effort to achieve fault tolerant quantum computing, Microsoft on Thursday unveiled its new error-correcting code, which uses four ...

The researchers have proven PLANAR's effectiveness on surface codes under particular noise conditions and plan to adapt it for non-planar graphs with finite genus, opening the door to broader use in ...

While noise can show up anywhere, ECC also can correct deterministic errors, such as those caused by faulty cells. This makes it possible to develop a design and test strategy that leverages some of ...

The quantum low-density parity check (QLDPC) codes, the “holy grail” of quantum error correction research and development for 30 years, have a breakthrough ...

Scalable quantum technologies require the ability to maintain and manipulate coherent quantum states over an arbitrarily long period of time. It is problematic then that the small quantum systems that ...

Error Correction Codes (ECC) play an essential role in safeguarding memory systems by detecting and correcting errors that arise from various sources, including ...

As with any electronic system, errors in the memory subsystem are possible due to design failures/defects or electrical noise in any one of the components. These errors are classified as either ...
