Probabilistic sparse synthesis of quantum operations
Probabilistic method enables exact quantum operations beyond current hardware limits.
Many operations, such as quantum computing gates or control pulses for NMR/MRI, cannot be feasibly implemented using current hardware or require coherence times that are unachievable. Oxford researcher’s new probabilistic approach enables the exact implementation of such operations.
Applications: Quantum computing, magnetic resonance imaging, nuclear magnetic resonance
| Features | Benefits |
|---|---|
| The method synthesises a desired quantum operation from a library of approximations that can be realised natively in quantum hardware | The approach allows quantum operations to be synthesised that would be impossible to implement directly in current quantum hardware |
| Uses classical computers to numerically pre-process the probabilistic scheme | Achieves orders of magnitude lower measurement overheads than other probabilistic schemes |
| Uses more generalised mathematical approach compared to other probabilistic techniques | Can be applied to a broad range of scenarios including quantum gate synthesis, quantum optimum control, and NMR and MRI operations |
| Doesn’t require both Clifford and T gate sequences unlike current probabilistic methods to synthesis quantum gates | It is directly compatible with error mitigation and advanced, randomised measurement techniques |
| Can exactly synthesis a quantum operation requiring only a small increase in the number of times the operation needs to be repeated |
