Alabama Patent of the Month – February 2024
Streamline Automation, LLC, an innovative force responsible for rocket engine test stands and various propellants, has unveiled a method that could reshape the landscape of quantum computing. The invention, a method for monitoring the state of a qubit device featuring a chiral nanocrystal, introduces a new era in quantum bits (qubits) and quantum computing systems.
The method involves measuring the voltage, current, or magnetic field of the chiral nanocrystal, assigning a superposition state if certain threshold values are met, and determining the direction of electron flow around the nanocrystal. What sets this invention apart is the utilization of a sub-micron sized Transition Metal Dichalcogenide (TMD) as the chiral nanocrystal, providing a topological path for current flow along the nanocrystal’s edge.
The incorporation of metal nanoparticles along the nanocrystal’s outside edge adds another layer of sophistication to the technology. This approach allows for the measurement of a voltage drop between electrodes, enabling the determination of the current’s direction. By applying a phase-shifted voltage and measuring magnetic fields induced by the current, the method becomes a comprehensive system for monitoring quantum states.
An intriguing aspect of Streamline Automation’s invention is its versatility. The method can be extended to multiple chiral nanocrystals, creating a quantum register. Each nanocrystal’s superposition or base state is determined independently, paving the way for complex quantum computations.
What makes this invention truly remarkable is its potential to operate at higher temperatures, reducing the need for extreme cryogenic conditions. This breakthrough addresses a significant challenge in quantum computing, allowing for more practical and feasible applications.
The invention has broad implications beyond quantum computing. Qubits described in this method can be utilized in atomic clocks, quantum navigation sensors, quantum key distribution systems, and even entanglement-enhanced microscopes.
