Cisco unveils software to accelerate quantum networks | Computer Weekly

"The company's Quantum Labs has launched what it claims is the industry's first software stack designed to network quantum computers together. While today's quantum machines are stuck at hundreds of qubits, most practical problems need millions, and so instead of waiting for a "perfect machine", Cisco said it is scaling out by connecting the computers we have now in a move that it boasts will accelerate real-world quantum applications by as much as decades."

"Cisco stressed that what makes its launch unique is that it accounts for quantum interconnect requirements between processors and supports distributed quantum error correction. Existing compilers only target circuits for single computers. The new one is said to compile circuits for network-connected computers, potentially made of heterogeneous quantum compute technologies, and can distribute that partitioned circuit across an entire datacentre of processors, all connected through a quantum network."

Cisco's Quantum Labs launched what it claims is the industry's first software stack to network quantum computers together. The stack compiles circuits for network-connected machines, accounts for quantum interconnect requirements, and supports distributed quantum error correction. The compiler can partition circuits across datacentre-wide, heterogeneous quantum processors connected by a quantum network, enabling scaling beyond single-machine qubit limits. The approach aims to scale out current quantum machines that have hundreds of qubits toward practical workloads that require millions. Potential use cases include large drug discovery algorithms, complex financial simulations, and research into new quantum algorithms and compute types.
