IQT The Quantum Dragon Podcast Episode 85 – We can solve problems 43 million times bigger than anyone else.

IQT The Quantum Dragon Podcast Episode 85 – We can solve problems 43 million times bigger than anyone else.

I spoke with Toby Cubitt, Co-Founder and CTO of Phasecraft about why we need algorithms when we don’t have hardware to run them on, a claim of 43,000,000X greater efficiency, the skillset needed to do what they do, quantum phase estimation (QPE) without controlled unitaries, the secret ingredient...

Why this matters
Why now

This podcast highlights recent advancements in quantum algorithm efficiency, particularly regarding hardware-agnostic solutions, which is critical as quantum hardware slowly matures.

Why it’s important

Claims of '43 million times greater efficiency' in quantum algorithms suggest a potential for dramatically accelerating solving complex problems, even with nascent quantum hardware, impacting various industries that rely on high-performance computing.

What changes

The focus is shifting towards sophisticated algorithmic development that can maximize output from existing and future quantum computing hardware, rather than solely waiting for hardware breakthroughs.

Winners
