  Quantum computers can outperform classical computers in certain tasks.
However, there are still many challenges to the current quantum computers such
as decoherence and fault tolerance, and other drawbacks such as portability and
accessibility. In this study, we circumvent these issues by realizing an analog
quantum emulation device (AQED) where each qubit state is represented by a
unique analog signal. It is possible to do this because previously it was shown
that Hermitian operations on a Hilbert space are not unique to quantum systems
and can also be applied to a basis of complex signals that form a Hilbert
space. Orthogonality of the complex signal basis can be maintained by
separating the signals into the frequency domain or the spatial domain. We
study both these approaches and present a comparison. We finally realize the
entire device on a UMC 180nm processing node and demonstrate the computational
advantage of an AQED by emulating Grover's search algorithm (GSA) and Quantum
Fourier Transform (QFT). We also present the equivalent quantum volume achieved
by this device.
