Selective Filtering for Fast Driving of Qubits - A simplified explanation of the abstract

This abstract first appeared for US patent application 17644424 titled 'Selective Filtering for Fast Driving of Qubits

Simplified Explanation

The patent application describes an apparatus that includes two qubits and a readout resonator, with each qubit having a different driving frequency. A filter is used to allow the first qubit to be driven at the second qubit's frequency. A drive unit is connected to the filter.

  • The apparatus includes two qubits with different driving frequencies.
  • A readout resonator is connected to both qubits.
  • A filter is used to enable the first qubit to be driven at the second qubit's frequency.
  • A drive unit is connected to the filter to control the qubits.

Potential applications of this technology:

  • Quantum computing: The apparatus can be used in quantum computers to manipulate and control qubits with different driving frequencies.
  • Quantum communication: The technology can be applied in quantum communication systems to enable efficient transmission and processing of quantum information.

Problems solved by this technology:

  • Frequency mismatch: The apparatus solves the problem of driving qubits with different frequencies by using a filter to match the driving frequency of one qubit to the other.
  • Efficient control: The technology allows for efficient control and manipulation of qubits with different driving frequencies, enabling more precise quantum operations.

Benefits of this technology:

  • Improved performance: The apparatus allows for better control and manipulation of qubits, leading to improved performance in quantum computing and communication systems.
  • Flexibility: The ability to drive qubits at different frequencies provides flexibility in designing and implementing quantum systems.
  • Compatibility: The technology can be integrated into existing quantum systems, enhancing their capabilities without requiring major modifications.


Original Abstract Submitted

An apparatus comprising a first qubit has a first driving frequency and a second qubit electrically connected to the first qubit, wherein the second qubit has a second driving frequency, wherein the second driving frequency is different than the first driving frequency. A readout resonator electrically connected to the first qubit and the second qubit and a filter electrically connected to the readout resonator, wherein the filter allows for the first qubit to be driven at the second driving frequency of the second qubit. A drive unit electrically connected to the filter.
