How to Build a Room-Temperature Quantum-Like Computer with Regular Electronics

This patent describes an integrated circuit and method for performing 'quantum analog computing' at room temperature using conventional electronic components like resistors, inductors, capacitors, and switches, arranged in a specific network.

What it covers

This integrated circuit performs 'quantum analog computing' by using a network of interconnected 'qubits' (Claim 1). Each qubit is built from standard electronic parts: resistors, inductors, capacitors, and a switch (Claim 1). These qubits are connected in a specific pattern, like a Hopfield network, where each qubit can connect to all others (Claim 2, 3). The circuit is designed to operate at normal room temperatures, between 0 and 30 degrees Celsius (Claim 6, 7). To compute, an initial voltage is set for each qubit (Claim 9), and the system then settles into a stable state. The final voltages on the qubits are measured to determine the solution to a problem (Claim 10). For example, this could be used to find the best solution in a complex optimization problem.

What it doesn't cover

• —Does not cover 'true' quantum computers that rely on quantum mechanical phenomena like superposition and entanglement for computation.
• —Does not cover quantum computing systems that require extremely cold (cryogenic) temperatures to operate.
• —Does not cover qubits that are specifically designed for error correction, as the claims state no qubit is used for this purpose (Claim 18).
• —Does not cover integrated circuits where individual qubits are not composed of resistors, inductors, capacitors, and a switch.
• —Does not cover connectivity topologies that are not 'all-to-all' or a Hopfield network, as these are specified in the claims (Claim 3, 11, 13).

The clever bit

The clever part is creating an 'analog of quantum behavior' using common electronic components (resistors, inductors, capacitors, switches) and operating them at room temperature. This avoids the extreme environmental and hardware challenges of true quantum computers, making quantum-inspired computation potentially much more practical.

Why it matters

This patent aims to make quantum-like computing more accessible. Traditional quantum computers require incredibly cold temperatures and specialized hardware, making them expensive and complex. By using conventional electronics like CMOS and operating at room temperature, this technology could significantly lower the cost and complexity of building systems that can tackle problems currently suited for quantum computers. This could open up new possibilities for solving complex optimization challenges in various industries.
