Approximate Quantum Random Access Memory Architectures

Understand

Quantum supremacy in many applications using well-known quantum algorithms rely on availability of data in quantum format.

• Quantum Random Access Memory (QRAM), an equivalent of classical Random Access Memory (RAM), fulfills this requirement.
• However, the existing QRAM proposals either require qutrit technology and/or incur access challenges.
• We propose an approximate Parametric Quantum Circuit (PQC) based QRAM which takes address lines as input and gives out the corresponding data in these address lines as the output.
