Michael Frank, a computer engineering researcher, left academia to join Vaire Computing, a startup focused on reversible computing as conventional chips run out of energy efficiency. Reversible computing, which aims to compute without using energy by reversing computations, offers up to a 4,000x energy-efficiency gain. Vaire’s first prototype chip, to be fabricated in 2025, aims to recover energy used in arithmetic circuits. Vaire’s long-term goal is a 4,000x improvement in performance, but challenges remain in integrating resonators on chips. The potential of reversible computing is exciting but requires overcoming various hurdles, which Vaire hopes to achieve in the next decade.
