I will discuss an alternative approach to quantum computation and simulation
that is ideally suited for today's sub-threshold-fidelity qubits, especially in
superconducting architectures. This approach makes use of the the n-dimensional
single-excitation subspace (SES) of a system of n tunably coupled qubits.
Although technically unscalable and inefficient in terms of the number of qubits
required, the SES approach allows n-dimensional unitary operations to be
implemented in a single shot, without the need to decompose into gates. The real
power of this approach is probably in its application to quantum simulation,
and I will show that for a particular class of time-dependent quantum simulation
problems a practical device that would vastly outperform classical machines
is within experimental reach.
