Google

Google has been a pioneering force in quantum computing, making headlines in 2019 with its quantum supremacy claim using the Sycamore processor.

The company is committed to advancing the field with a focus on superconducting qubits, which are at the heart of its quantum chips.

Google Quantum Chips:

Sycamore: The Sycamore chip (54 qubits, but one qubit was unusable during the test) solved a specific computational task in 200 seconds—a task that would have taken the fastest classical supercomputer 10,000 years.

Willow: Willow (105 qubits) incorporates superconducting qubits like Sycamore, but its key innovation is quantum error correction—a critical step toward achieving scalable, practical quantum systems. Willow addresses the challenge of qubit errors by implementing advanced error correction techniques that reduce the error rate as the number of qubits increases.

 

Major Achievements of Google Quantum Chips:

1. Quantum Error Correction: Willow is a landmark achievement in quantum error correction. In tests, it has demonstrated an exponential reduction in errors, achieving what is known as being “below threshold.” This means that Willow can scale up the number of qubits without a corresponding increase in errors, a breakthrough that could make large-scale quantum systems more feasible.

2. Real-Time Error Correction: Willow is also one of the first systems to implement real-time error correction on a superconducting quantum system. This feature is crucial because it ensures that quantum computations can continue without being destroyed by errors before they are corrected.

3. Improved Performance: Willow’s performance in random circuit sampling—a benchmark that measures quantum processor performance—has been impressive. Google reported that Willow could perform computations in under 5 minutes that would take 10 septillion years on the fastest classical supercomputers, further confirming its potential to solve problems that are out of reach for classical systems.

4. Google focuses on developing quantum algorithms and the Quantum AI platform to apply quantum computing to areas like chemistry, materials science, and artificial intelligence.
