About

ApexQuantum is an early-stage quantum computing software company developing an optimizing compiler for quantum computers. Its compiler translates and transforms quantum algorithms into circuits that run efficiently on real quantum hardware, targeting both NISQ-era machines and forthcoming fault-tolerant systems. The company holds an NSF SBIR Phase I award of roughly $305,000 for the work. It was founded in 2024 and operates from Ellicott City, Maryland.

Hardware-agnostic circuit optimization aimed at cutting quantum computational latency by one to two orders of magnitude, lowering the barrier to entry for developers writing quantum programs.
