DURIP Support for Holographic Analog Simulations and Multi-Qubit Operations with Trapped Ions
Abstract
Quantum computers hold the promise of substantially impacting applications both in the civilian and in the military realm. A quantum processor would some problems to be solved with a superpoly-nomial improvement in the computational complexity with respect to their classical counterparts. However the class of problems amenable to quantum advantage still remains unknown. Promising near-term applications for which quantum processors can provide a significant advantage over clas-sical computers are calculations of low-temperature properties of correlated materials, dynamics of electrons in molecules, simulating lattice gauge theories of particle physics and combinatorial optimization. One of the most promising platforms with which to realize practical quantum com-puters and simulators are trapped ions. However, despite robust qubits and long coherence times, trapped-ion technology is not yet ready to fulfill these promises: for example the efficient encoding of combinatorial optimization problems, lattice gauge theories, and several important models with topological order require multi-qubit interactions, which are not yet readily available in trapped-ion systems. Moreover, large scale quantum algorithms will inevitably need Quantum Error Correction (QEC), which requires high fidelity mid-circuit detection of errors via projective measurements of quantum correlations (error syndromes), as well as conditional feedback to apply corrections. In this project we aim to fundamentally enhance the quantum operations toolbox available for trapped-ion hardware, introducing parallel and multi-qubit gates, mid-circuit hiding and measure-ments operations, as well as new holographic analog quantum simulation solutions to allow a more efficient mapping of problems of practical interest onto the quantum hardware. This present DURIP proposal seeks funding for equipment that will be used to pursue a collaborative effort between Rice University and Duke University. The purchased equipment will be used at Rice University in PI Pagano’s lab for a new laser infrastructure to use the metastable states of 171Yb+ ions to perform shelving and qubit hiding operations. This program plans to enhance dramatically the capabilities of state-of-the-art trapped-ion quantum processors towards the long-term goal of enabling fault tolerance quantum computing. This pro-gram combines partial measurements, a necessary ingredient for quantum error correction protocols, and analog protocols and more efficient gates to generate entanglement in trapped-ion s ystems. If successful, these advances will allow to use trapped ions to tackle applications of strategic interest for the Department of Defense, such as resource allocation, logistics, networks, transportation and even financial models
