Multi-State Qubit Readout with Permutation Sequences - A simplified explanation of the abstract

This abstract first appeared for US patent application 18483758 titled 'Multi-State Qubit Readout with Permutation Sequences

Simplified Explanation

The abstract describes systems and methods for measuring quantum states of qubits with more than two levels. A quantum computer applies quantum gates and shuffling sequences to the qubits, measures the state of the qubits using a readout apparatus, and determines an average occupation for the quantum states of the qubits.

• Quantum algorithm execution: The method involves applying quantum gates to qubits to execute a quantum algorithm.
• Shuffling sequences: Shuffling sequences are applied to the qubits to manipulate their states.
• Readout apparatus: The state of the qubits is measured using a readout apparatus.
• Average occupation determination: The method determines the average occupation of the quantum states of the qubits using the readout states for each shuffling sequence.
• Subset of quantum states: The readout states correspond to a state in a subset of the quantum states of the qubits.

Original Abstract Submitted

Systems and methods for measuring quantum states of qubits with more than two levels are provided. A method can include, for a plurality of shuffling sequences, applying, by a quantum computer, one or more quantum gates to the one or more qubits to execute a quantum algorithm; applying, by the quantum computer, a shuffling sequence to the one or more qubits; and measuring, using a readout apparatus, the state of the one or more qubits to determine a readout state. The method can further include determining, by a classical computer or the quantum computer, an average occupation for one or more of the quantum states of the one or more qubits using the readout states for each of the shuffling sequences. The readout states can correspond to a state in a subset of the quantum states of the one or more qubits.
