Quantum computers promise to solve problems far beyond the reach of classical machines, from simulating new materials to transforming AI.
But one key challenge stands in the way: speed.
To be reliable, quantum computers must perform calculations and error corrections before their fragile quantum bits, or qubits, lose coherence.
Now, MIT researchers have built a new superconducting circuit that could dramatically speed up this process.
At its core is a newly invented component, the “quarton coupler,” which enables a record-breaking level of interaction between light and matter, crucial for reading and controlling qubits.
This breakthrough could make operations up to 10 times faster, bringing fault-tolerant, real-world quantum computing a major step closer.
