Tensor Networks for Simulating Quantum Circuits on FPGAs

Understand

Most research in quantum computing today is performed against simulations of quantum computers rather than true quantum computers.

• Simulating a quantum computer entails implementing all of the unitary operators corresponding to the quantum gates as tensors.
• For high numbers of qubits, performing tensor multiplications for these simulations becomes quite expensive, since $N$-qubit gates correspond to $2^{N}$-dimensional tensors.
• One way to accelerate such a simulation is to use field programmable gate array (FPGA) hardware to efficiently compute the matrix multiplications.
