Advancing Quantum Computers for (and with) Quantum Thermodynamics

Progress in both quantum computation and quantum thermodynamics (QT) has unfolded rapidly over the last few decades. Their apparent co-development is not mere coincidence as each contributes to the advancement of the other. The performance of a quantum computer (QC), as a quantum information processing device, is fundamentally bound by the laws of Thermodynamics as elucidated by Landauer. Thus, a better understanding of QT, (i.e., the thermodynamics of systems and devices operating in the quantum regime) can inform best practices for the implementation and performance optimization of QCs. At the same time, the QC, with its precise control over individual quantum constituents, offers a game-changing new platform for exploring QT. An elegant synergy therefore exists whereby results from QT may be used to improve the operation of QCs, and QCs can be used to improve our fundamental understanding of QT. The goal of this Project is therefore to perform research at the intersection of these two fields, using progress in one field to further advances in the other. Specifically, we applied computational cooling techniques developed within QT to cool qubits on QCs to improve their performance; used a QC to demonstrate a key step in performing a heretofore inaccessible experimental validation of the Jarzynski equality in open quantum systems; we wrote a perspective and roadmap for current and future research at the nexus of QT and QC; and finally, analyzed the performance of feedback-controlled quantum thermal engines in terms of efficiency and work output (which could be implemented with qubits) using the principles of QT.

Цел на проекта

While thermodynamics is one of the most well-established physical theories, there is much that remains to be worked out in its extension to the quantum realm. With the miniaturization of electronics down to the nanoscale, along with the emergence of quantum technologies, it is becoming essential to gain a better understanding of thermodynamics at the quantum level. The emergence of quantum computers (QCs) in the last decade provides a game-changing new tool for research into quantum thermodynamics (QT). Furthermore, still in nascent stages, QCs stand to gain vast improvements in performance from new insights derived from QT. An elegant synergy therefore exists whereby (i) QCs can be used to improve the fundamental understanding of QT and (ii) principles from QT may be used to improve the reliability of QCs. Inspired by this synergy, this proposal includes two thrusts to advance progress along these two fronts. For the first thrust, I aim to develop new algorithms packaged into well-documented, open-source software for simulating thermal properties and behaviors of quantum systems on QCs. This work will culminate in attempting the first-ever experimental validation fluctuation relations (theoretical pillars of QT) for open quantum systems on a QC. For the second thrust I aim to use the principles of QT to implement an algorithmic cooling scheme that can improve the overall performance of qubits for any desired application on a QC. This work will culminate in attempting the first-ever experimental demonstration of algorithmic cooling on a QC. The proposed research requires an interdisciplinary approach encompassing quantum information and computation; thermodynamics and statistical mechanics; and computational science (CS). The complementary expertise and experience of the experienced researcher (in QC and CS) and the supervising host (in QT) will foster a productive two-way transfer of knowledge and facilitate the success of the research goals.
