Just LOVE the "Advanced Quantum Algorithms" lecture notes of Stacey Jeffery!!! homepages.cwi.nl/~jeffery/not... Everyone teaching quantum computing should read this paragraph out loud to their students! homepages.cwi.nl/~jeffery/not...
![Many of the potential applications of Hamiltonian simulation are not algorithms themselves, but
rather, the idea that having a better understanding of certain physical or chemical systems would likely
lead to new scientific and technological breakthroughs. Some of these are well worked out ideas (for
example, nitrogen fixation [RWS+17]), but many of them are very tenuous, which unfortunately does
not stop popular science news, and technology-enthusiasts who have decided to make a career talking
a lot about quantum computing without really understanding it, from treating such applications as
being just around the corner. You will find headlines and ted talks claiming quantum computers can
solve every futuristic-sounding problem, including fixing climate change [mtl], curing cancer [Kak24],
and finding the secret to immortality [Gre20]. I mean, science could solve any of these (but could it?),
and faster Hamiltonian simulation would mean we can do better science, so. . . The reality is, there
probably will be many applications to being able to simulate physical systems, but we do not yet know
what they will be. We will not discuss applications of Hamiltonian simulation in this course, but it
is important to understand that there is a lot of hype around quantum computing, some of which is
justified, and some of which is not.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:tepknacn7qtpcddry35b3g2x/bafkreibcs6y26budwxemzcdm4sxf4ltootd5f76rwvr4efnbebvrc2nm3a)
Caught these rare Light Pillars dancing in the sub-zero air. It happens when flat ice crystals (diamond dust) turn the sky into a giant mirror, reflecting city lights into vertical beams. Pure magic at -20°C! 🌌📸#LightPillars #AtmosphericOptics #NightPhotography #WinterMagic

See our work on quantum batteries! We shown that fluctuion of work and power follow a tradeoff relation in quantum batteries. Additional we have also found that high power is accompanied by high fluctuations in power. #quantumtech #energystorage #quantum #batteries #quantumdevices #quantumscience

This year, I published articles on quantum speed limits, thermodynamics, quantum dynamics, and non Markovianity. #2025
The well known time-energy uncertainty relation follows from the Robertson uncertainty relation, also known as the Mandelstam Tamm bound. We derive an exact time-energy uncertainty relation, which is an exact relation rather than an inequality. @PhysRevA journals.aps.org/pra/abstract...
Exact quantum speed limits
The traditional quantum speed limits are not attainable for many physical processes, as they tend to be loose and fail to determine the exact time taken by quantum systems to evolve. To address this w...
