Infleqtion And Nvidia Reduce Physical-to-Logical Qubit Ratio in Quantum Computers

To improve error correction, multiple entangled physical qubits are grouped together to create logical qubits.

Given that, reducing the number of physical qubits per logical qubit is important.

Sheir Yarkoni, director of quantum software for Qarakal Quantum, told The Next Platform that the startup’s new Pangaea architecture will reduce the physical qubit requirements by 10 times.

“High-rate qLDPC codes change that arithmetic by encoding multiple logical qubits in one block while keeping each stabilizer check sparse.

In addition, the workflow that was compiled ensure two distinct logical qubit owners within a single encoded block.
