While there are some quantum hardware vendors that offer on-premises installations, “most organizations prefer to access quantum computing systems via private quantum cloud offerings from quantum hardware vendors or public quantum cloud offerings from quantum cloud service providers,” she said.
Streamlining the quantum system
The system, developed jointly by Fujitsu and Osaka, introduces a streamlined process for converting logic gates, the fundamental operations of quantum computing, into physical gates which operate the qubits. It also has acceleration technology that minimizes computing time by dynamically changing the operational procedures of the qubits. The features represent improvements added to address issues discovered in a joint quantum computing architecture they introduced in March of last year.
Quantum computers rely on the quantum mechanics of qubits, however, qubits are fragile and susceptible to environmental noise. This has created a scenario in which “gate-based quantum computing hardware vendors have been challenged in their ability stabilize and scale to the number of qubits that is thought to be needed for these computations,” which is estimated to be around 1 million, West explained.
.
Part of the reason for this is that physical qubits are used for two functions during the computation sequence: gate operations and error correction. For error correction, a cluster of physical, or logical, qubits must be dedicated to error correction only, she explained. This reduces the number of qubits available for quantum computation, and hence the ability to use the systems to solve complex problems.
Potential to improve error correction
As suggested by the new technology, the development of a quantum circuit generator could ease the process of converting logical qubits that are being used for error correction to physical qubits used for computations, West observed.
