A Passive QRAM Query Used Polylogarithmic Energy
A time-independent Hamiltonian blueprint targets logarithmic query energy and log-squared runtime.
Summary
A time-independent Hamiltonian blueprint targets logarithmic query energy and log-squared runtime.
The proposed QRAM construction stores N memory bits behind an n-qubit address and evolves a pre-manufactured, time-independent four-local Hamiltonian. The authors prove O(log N) energy and O(log-squared N) runtime per query, with O(N) Hamiltonian terms and at most four terms touching any qubit. It is a feasibility blueprint, not an experimental memory device.
Why it matters
A time-independent Hamiltonian blueprint targets logarithmic query energy and log-squared runtime.
Limits and context
- It is a feasibility blueprint, not an experimental memory device.
