“It becomes very difficult to suppress noise to very small levels, and that becomes a problem in quantum computing,” she said. “The most promising candidate was this quantum error correction, where we take the physical qubits, make a logical qubit.” Logical qubits are groups of physical q...
As quantum technologies advance, other possible routes for error correction are by encoding qubits in harmonic oscillators and molecules, alongside the “traditional” approach of using arrays of physical qubits. Oscillator and molecular qubits possess their own mechanisms for error correction, and could ...
“For quantum computing, these errors are really an issue,” says Dr. Sangkha Borah, a postdoctoral researcher in theQuantum Machines Unitled by Professor Jason Twamley at theOkinawa Institute of Science and Technology(OIST). “If we can figure out how to accurately perform QEC, we might hav...
Quantum computing is an emerging technology that uses phenomena occurring on an atomic level to resolve complex problems that are beyond the realm of classical computers. Forming the core of superconducting quantum processors, this technology has made it possible to deliver chipsets with increasing compu...
Google’s research thus focused on quantum error correction. In the process, Google said it has been able to cut down the error rate even while increasing the number of qubits. “We published results showing that the more qubits we use in Willow, the more we reduce errors, and the mor...
There are ways around this ("quantum error correction"), but they introduce a great deal more complexity. There's also the fundamental issue of how you get data in and out of a quantum computer, which is, itself, a complex computing problem. Some critics believe these issues are ...

“In the future, we’ll encounter challenges that cannot be met using current methods. Quantum computing will play an important role in solving these kinds of problems. For example, the quantum computers of the future will be able to accurately model viruses and pharmaceuticals, or design new ...
, in some cases by much more than the pandemic correction seen more broadly across tech companies. it’s not quite clear what the first killer apps of quantum computing will be, or when they will appear. but there’s a sense that whichever company is first to make these machines useful ...
quantum information cannot be cloned or copied due to the no-cloning theorem (which states that it is impossible to create an independent and identical copy of an arbitrary unknown quantum state). Therefore, a new error correction method is required for quantum computing systems. Numerous companies...
