Scientist To Build Error-free Quantum Computers

Scientists are likely to build quantum computers to shrink error rates which are common in computers, according to a media report on Wednesday.

The new computers will be a combination of multiple fallible qubits into one improved qubit, which can be called a logical qubit to make calculations and will solve almost all impossible errors, which the traditional computer failed in a way.

Such advanced quantum machines will require the use of error correction to dramatically shrink error rates. While scientists have previously demonstrated and claimed to detect and correct simple errors in small-scale quantum computers, error correction has never evolved from the primary stages.

Meanwhile, the scientist doesn’t mean building a fully error-corrected quantum computer, however, they demonstrate that error correction fundamentally works, said physicist Julian Kelly of Google Quantum AI according to reports.

However, studies say, logical qubits store information redundantly in multiple physical qubits. that allows the quantum computer to check the cropped mistakes and fix them on the fly. Ideally, the study stated, the larger the logical qubit, the smaller the error rate. But if the original qubits are faulty, adding in more of them will cause more problems than it solves.

The scientist has used Google’s Sycamore quantum chip, to study two different sizes of logical qubits, one consisting of 17 qubits and the other of 49 qubits. But still, they fail to achieve the milestones in quantum computation.
