Researchers at Harvard University, MIT, QuEra Computing, and NIST have developed a prototype quantum computer with 48 logical qubits, a significant advancement in quantum computing. The system uses 228 physical qubits, demonstrating a new approach to quantum error correction and logical qubit design.
The key innovation is a new quantum error correction code that distributes information across multiple physical qubits, making the system more robust against errors. The researchers also developed a new algorithm to choreograph the qubits into complex quantum circuits.
This work represents a major step towards practical quantum computing, as it demonstrates a scalable approach to building large-scale quantum systems. The next steps will involve further optimization and testing of the system, with the goal of achieving quantum advantage – performing computations that are infeasible for classical computers.
The research was published in Nature and could have significant implications for quantum technologies, potentially enabling breakthroughs in cryptography, drug discovery, and optimization problems.
