Researchers at Princeton University have developed a new way to make quantum computers less prone to errors. They used neutral atoms to create qubits that can detect and fix mistakes more easily.
Quantum computers are super-fast machines that use the laws of physics to process information. Unlike regular computers, they don't store data as simple 0s and 1s, but as special units called qubits that can exist in many states at once.
The problem is that qubits are very sensitive to their surroundings, which makes them prone to errors. This means that quantum computers often produce wrong answers or crash altogether.
A team of researchers from Princeton University has come up with a new approach to make quantum computers more reliable. They used special atoms called ytterbium-171, which can exist in an excited state for a long time. These atoms were used to create qubits that produce a specific type of error called erasure errors.
Erasure errors are like a warning sign that says 'this qubit is not working properly.' The researchers then developed a way to correct these errors using a special code that stores two logical qubits in four physical qubits. This means that if one qubit makes a mistake, the other can fix it.
The team's study shows that this new approach can make quantum computers more reliable and efficient. They are now planning to test their method on a larger scale and see how well it works.
