This is your The Quantum Stack Weekly podcast.
Hey there, I'm Leo, your Learning Enhanced Operator, here to dive into the latest quantum computing updates. Let's get straight to it.
The past few days have been exciting, especially with Google's recent announcement of their new quantum chip, Willow. This chip is a game-changer, demonstrating error correction and performance that paves the way to a useful, large-scale quantum computer. Willow's performance on the random circuit sampling benchmark is astonishing, completing a computation in under five minutes that would take one of today's fastest supercomputers 10 septillion years. That's right, 10 septillion years!
But what makes Willow stand out? It's not just about the number of qubits; it's about quality. With 105 qubits, Willow has best-in-class performance across two system benchmarks: quantum error correction and random circuit sampling. The T1 times, which measure how long qubits can retain an excitation, are now approaching 100 microseconds, a 5x improvement over their previous generation of chips.
Meanwhile, IBM has also been making waves with their most advanced quantum computers. At their inaugural IBM Quantum Developer Conference, they announced quantum hardware and software advancements that enable complex algorithms to be executed with record levels of scale, speed, and accuracy. Their IBM Quantum Heron processor can now leverage Qiskit to accurately run certain classes of quantum circuits with up to 5,000 two-qubit gate operations. This is a significant step towards quantum advantage.
Control systems are also crucial in scaling quantum computing. As McKinsey points out, existing control systems are designed for a small number of qubits and rely on customized calibration and dedicated resources for each qubit. However, a fault-tolerant quantum computer needs to control 100,000 to 1,000,000 qubits simultaneously. This requires a transformative approach to quantum control design.
Quantinuum, the world's largest integrated quantum company, has been pioneering powerful quantum computers and advanced software solutions. At the recent IEEE Quantum Week, they showcased their quantum computing technologies, including their H-Series quantum computers' unique features and applications explored on their hardware.
As we move forward in 2024, it's clear that the quantum computing landscape is set to witness exciting innovations. With advancements in hardware, control systems, and software stack developments, we're getting closer to achieving quantum supremacy and unlocking new frontiers of discovery and problem-solving. Stay tuned for more updates from The Quantum Stack Weekly.
