Harvard's Quantum Breakthrough: First Computer Runs 2+ Hours Non-Stop
Harvard University has made a groundbreaking achievement in quantum computing. The team, led by Mikhail Lukin, has developed the first quantum computer to run continuously for over two hours without any downtime. This significant milestone could accelerate the practical use of quantum applications and improve the resilience of current encryption schemes.
The quantum computer, hosting 3,000 qubits, maintains its quantum state by injecting 300,000 atoms every second. This rate outpaces the loss of qubits, enabling the system to run potentially indefinitely. The system uses a combination of optical tools, including a lattice conveyor belt and optical tweezers, to replenish lost qubits in real-time, actively repairing errors and allowing for continuous operation.
This breakthrough removes the bottleneck of frequent restarts, improving the viability of quantum computing as a service model. It also paves the way for scaling to millions of qubits while maintaining continuous operation. The dynamic, fault-tolerant architecture could test the resilience of current encryption schemes against quantum attacks in real-time, informing the transition to post-quantum standards. In healthcare, real-time quantum simulations could model complex biological systems, accelerating drug discovery pipelines.
Harvard's achievement accelerates the timeline for practical quantum applications, with fully autonomous, never-ending quantum computers potentially operational in three years. This could significantly improve the fidelity of predictive models in climate modelling and enhance our understanding of complex biological systems. The continuous operation of quantum computers opens up new possibilities for real-time simulations and data processing.
