QUANTUM DOT BASED QUBIT DEVICES WITH ON-CHIP MICROCOIL ARRANGEMENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240330726 titled 'QUANTUM DOT BASED QUBIT DEVICES WITH ON-CHIP MICROCOIL ARRANGEMENTS

The patent application describes quantum dot devices that use microcoil arrangements to provide a gradient magnetic field for individually addressing qubits on the same chip.

• Microcoil arrangements integrated on the same chip as quantum dot qubits enable improved control over magnetic fields and their gradients.
• The devices help target individual qubits more accurately in frequency, minimize the effects of charge noise, and allow for scalability in the number of quantum dots included.

Potential Applications: - Quantum computing - Quantum information processing - Advanced data encryption

Problems Solved: - Improved control over magnetic fields for quantum dot qubits - Minimization of adverse effects of charge noise - Enhanced scalability in the number of qubits on a chip

Benefits: - Better frequency targeting of individual qubits - Reduced qubit decoherence due to charge noise - Scalability in the number of quantum dots on a chip

Commercial Applications: Title: Quantum Dot Devices for Enhanced Quantum Computing This technology could revolutionize quantum computing by providing better control over qubits, reducing decoherence, and enabling scalability in quantum dot devices. This could have significant implications for industries relying on advanced computing power.

Questions about Quantum Dot Devices for Enhanced Quantum Computing: 1. How do microcoil arrangements improve control over magnetic fields in quantum dot devices? 2. What are the potential long-term benefits of using these devices in quantum computing applications?

Original Abstract Submitted

an array of quantum dot qubits (e.g., an array of spin qubits) relies on a gradient magnetic field to ensure that the qubits are separated in frequency in order to be individually addressable. furthermore, a strong magnetic field gradient is required to electrically drive the electric dipole spin resonance (edsr) of the qubits. quantum dot devices disclosed herein use microcoil arrangements for providing a gradient magnetic field, the microcoil arrangements integrated on the same chip (e.g., on the same die or wafer) as quantum dot qubits themselves. unlike previous approaches to quantum dot formation and manipulation, various embodiments of the quantum dot devices disclosed herein may enable improved control over magnetic fields and their gradients to realize better frequency targeting of individual qubits, help minimize adverse effects of charge noise on qubit decoherence and provide good scalability in the number of quantum dots included in the device.
