TITLE:
Quantum Computing on Memristive Nanoelectronic Networks: Challenges and Opportunities
ABSTRACT:
Quantum algorithms exploit the distinctive features of superposition and entanglement to address issues that are challenging or unfeasible for classical computers. Despite quantum computers being in their nascent stage, resulting in a limited number of operational quantum computers, numerous quantum computer simulators exist that enable researchers and developers to explore quantum algorithms and quantum gates. Nonetheless, these simulators are implemented at the software level, which constrains them by the performance limitations of classical computers, particularly regarding memory due to the exponential demands as the number of simulated qubits rises, and in terms of the execution time of quantum algorithms. This presentation proposes hardware accelerators for quantum computations that leverage the intrinsic characteristics of memristor devices, which can be densely organized in crossbars and execute in-memory computations concurrently, with the goal of exceeding the limitations of software counterparts. This study proposes a memristive crossbar system that effectively simulates quantum computations. The suggested circuit is incorporation of quantum entanglement and superposition enables the execution of any quantum algorithm reliant on dense coding and extensive parallelism. The constructed circuit can embody various quantum gates and establishes a universal set of quantum gates. We demonstrate the implementation of quantum algorithms on the same memristor crossbar configuration by reprogramming the crossbars to align with the functionality of the quantum gates constituting the relevant quantum algorithm and by utilizing their vector-matrix multiplication capabilities.
