Analog computation has an old history going back to mechanical differential analyzers for solving Ordinary Differential Equations. These equations can be used model Hilbert space that is used in Quantum Computing. It was realized that the computational operation called quantum computing does not need quantum systems by Paul Benioff in 1980; however, the analog approaches to solving Hilbert space projections have been mostly of academic curiosity. The Field Programmable Analog Array is reprogrammable analog hardware that allows for general purpose analog computing, and is uniquely suited to create a platform for Hilbert Space Computing.
Benefit: The primary benefit of Hilbert space computing in analog is room-temperature operation with devices that leverage the 40-years of investment in the semiconductor industry. No custom cryogenic systems are required as everything can be created on a standard CMOS fab.
