Berkeley Lab Advances Quantum Stack for 1,000-Fold Performance Gain in Error-Corrected Systems
2 articles · Updated · Lawrence Berkeley National Laboratory (.gov) · May 27
Berkeley Lab said it is pushing beyond qubits alone, coordinating hardware, cryogenics, control electronics and software with industry and academic partners to build error-corrected quantum systems.
Below 20 millikelvin, superconducting processors need ultra-clean microwave control, and researchers say any weak link in that stack can cap performance even if qubit coherence improves.
A key scaling hurdle is wiring: one or more wires per qubit works for a few dozen qubits, but not for the thousands needed for second-generation machines.
Those larger systems will rely heavily on classical computing—and likely AI tools such as Berkeley Lab's QubiCML—to detect and correct errors in real time.
At its Advanced Quantum Testbed, Berkeley Lab is targeting roughly 1,000 times better processor performance, aiming to enable future simulations in particle physics, materials and quantum chemistry.
With qubit requirements now plummeting, is the race for a fault-tolerant quantum computer nearly over?
As quantum development accelerates, will a critical shortage of experts become the biggest barrier to a quantum future?
