COMBINED TABLE LOOKUP AT QUANTUM COMPUTING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17806923 titled 'COMBINED TABLE LOOKUP AT QUANTUM COMPUTING DEVICE

Simplified Explanation

The abstract describes a quantum computing device that includes a table lookup circuit. This circuit can perform table lookup operations on two inputs simultaneously and write the combined output to a register. The output consists of multiple qubits from each table lookup operation.

  • The quantum computing device has a table lookup circuit that can process two inputs at the same time.
  • The circuit performs table lookup operations on the inputs in parallel.
  • The combined output of the circuit is stored in a register.
  • The output includes qubits from both table lookup operations.

Potential Applications

  • Quantum database search: The device can be used to search large databases in parallel, providing faster results compared to classical computers.
  • Machine learning: Quantum machine learning algorithms often involve table lookups, and this device can enhance the speed and efficiency of such algorithms.
  • Cryptography: Quantum computing has the potential to break traditional cryptographic algorithms, but this device can be used to develop more secure quantum-resistant cryptographic techniques.

Problems Solved

  • Parallel processing: The device allows for simultaneous processing of multiple inputs, increasing the speed and efficiency of computations.
  • Quantum algorithm optimization: By performing table lookup operations in parallel, the device can optimize the execution of quantum algorithms that rely on such operations.

Benefits

Original Abstract Submitted

A quantum computing device is provided, including a table lookup circuit configured to receive a first table lookup input and a second table lookup input. The table lookup circuit may be further configured to perform a first table lookup operation on the first table lookup input and a second table lookup operation on the second table lookup input in parallel such that a combined table lookup output is written to a combined output register. The combined table lookup output may include a plurality of first table lookup output qubits of the first table lookup operation and a plurality of second table lookup output qubits of the second table lookup operation.
