Analog Counterdiabatic Quantum Computing: Accelerating Hard Problem Solving with Neutral Atoms

This groundbreaking research introduces Analog Counterdiabatic Quantum Computing (ACQC) for neutral atom processors, significantly mitigating non-adiabatic errors. Applied to the Maximum Independent Set (MIS) problem, ACQC demonstrates over 3-fold speedup and enhanced solution quality with up to 100 qubits, paving the way for scalable quantum advantage in industrial applications.

Executive Impact Summary

Analog Counterdiabatic Quantum Computing (ACQC) dramatically improves the efficiency and reliability of neutral atom quantum processors for complex combinatorial optimization problems like MIS. By analytically derived counterdiabatic terms, ACQC reduces non-adiabatic errors, achieving faster convergence and higher fidelity compared to standard adiabatic methods. This enables robust solutions within shorter coherence times, crucial for current hardware limitations, and scales effectively for larger problem instances. The method's ability to provide high-quality solutions rapidly positions it as a key enabler for quantum advantage in real-world industrial applications, from logistics and scheduling to finance and AI.

MIS Problem

The Analog Counterdiabatic Quantum Computing (ACQC) protocol introduces additional, analytically derived terms to the fast-evolving adiabatic Hamiltonian. These terms are designed to suppress non-adiabatic transitions between eigenstates, thereby guiding the quantum system more reliably towards the desired ground state, which encodes the solution to combinatorial optimization problems like the Maximum Independent Set (MIS). This approach enhances computational fidelity and allows for faster problem solving within limited coherence times.

Neutral atom processors, utilizing arrays of atoms trapped in optical tweezers and leveraging strongly interacting Rydberg states, serve as a promising platform for analog quantum computing. Each atom acts as a qubit, and their interactions natively encode solutions to optimization problems. The ACQC protocol is specifically tailored for these platforms, manipulating Rabi frequency, detuning, and phase of driving lasers to implement the counterdiabatic corrections without requiring additional many-body interaction terms or extensive iterative optimization.

The Maximum Independent Set (MIS) problem is a fundamental combinatorial optimization problem with wide-ranging industrial applications, including network resilience, resource allocation, scheduling, and computational biology. The ACQC protocol demonstrates its effectiveness by solving MIS instances with up to 100 qubits, showcasing significant speedup and improved solution quality compared to conventional adiabatic methods. This highlights the practical relevance and scalability of ACQC for real-world enterprise challenges.
