Whats really important is that if we keep making these devices bigger and bigger, we also need the performance to continue improving, in order for us to be able to realize some of these really complex algorithms, where each qubit is needed to be able to implement billions of gates, said Bluvstein. To be able to implement these billions of gates, we really need to start, now in the field, switching over to not only testing our algorithms with physical qubits and learning about how quantum algorithms work, but begin testing our algorithms with logical qubits. We need to determine how error-corrected algorithms work because we know that in order to, for example, solve really big problems, such as really big chemistry problems, we need things on the scale of more than a billion gates. And were never going to be able to achieve this with our physical qubits, so we need to focus on error-correcting algorithms

In a groundbreaking exclusive interview with TQI, scientists from Harvard University and QuEra have revealed that the key to practical quantum computing may lie in the innovation of shuttling qubits and harnessing parallelism. The importance of improving performance in quantum devices is paramount, as the complexity of algorithms requiring billions of gates necessitates a shift towards testing with logical qubits. Dr. Bluvstein emphasized the need to explore error-corrected algorithms to tackle massive problems like complex chemistry simulations, which demand scalability beyond the capabilities of physical qubits. This shift in focus towards error correction is crucial for the advancement of quantum computing and the realization of its potential in solving real-world challenges.
