MEASURING A N-DIMENSIONAL QUANTUM SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240119328 titled 'MEASURING A N-DIMENSIONAL QUANTUM SYSTEM

Simplified Explanation

The present disclosure relates to a quantum system of dimension m comprising a transmon device. The transmon device is in an initial state which is restricted to a state of a n-dimensional quantum system embedded in the quantum system, where n<m. The transmon device is configured to receive a sequence of pulses for transforming the initial state to a state of the quantum system. The transmon device is connected to a readout that is configured to perform a projection-valued measure (PVM) of the transmon device in its state.

• Quantum system with a transmon device
• Initial state restricted to a n-dimensional quantum system
