  Quantum information science is a growing field that promises to take
computing into a new age of higher performance and larger scale computing as
well as being capable of solving problems classical computers are incapable of
solving. The outstanding issue in practical quantum computing today is scaling
up the system while maintaining interconnectivity of the qubits and low error
rates in qubit operations to be able to implement error correction and
fault-tolerant operations. Trapped ion qubits offer long coherence times that
allow error correction. However, error correction algorithms require large
numbers of qubits to work properly. We can potentially create many thousands
(or more) of qubits with long coherence states in a storage ring. For example,
a circular radio-frequency quadrupole, which acts as a large circular ion trap
and could enable larger scale quantum computing. Such a Storage Ring Quantum
Computer (SRQC) would be a scalable and fault tolerant quantum information
system, composed of qubits with very long coherence lifetimes. With computing
demands potentially outpacing the supply of high-performance systems, quantum
computing could bring innovation and scientific advances to particle physics
and other DOE supported programs. Increased support of R$\&$D in large scale
ion trap quantum computers would allow the timely exploration of this exciting
new scalable quantum computer. The R$\&$D program could start immediately at
existing facilities and would include the design and construction of a
prototype SRQC. We invite feedback from and collaboration with the particle
physics and quantum information science communities.
