Quantum Memory: a missing piece in quantum computing units

Memory is an indispensable component in classical computing systems. While the development of quantum computing is still in its early stages, current quantum processing units mainly function as quantum registers. With the rapid scaling of qubits, it is opportune to explore the potential and feasibility of quantum memory across different substrate device technologies and application scenarios. In this talk, we provide a full design stack view of quantum memory, from the elementary building blocks: quantum memory cells, to quantum memory devices and the quantum memory function units in the architecture of quantum processing units. We further propose programming models for the quantum memory units and discuss their possible applications.
