Marco Piani @marcopiani.bsky.social · 28/07/2026It does not end there: more highly scited papers in quantum information saw AI play a major role, solving long-standing problems, like the ones about the two-copy distillability of Werner states, something I worked on in my academic past. 160
Marco Piani @marcopiani.bsky.social · 28/07/2026All the top papers on Scirate saw AI play some role, in some cases a major one. These screenshots are from the top 4 papers, in order. A major role played by AI in at least three of them. 271

Marco Piani @marcopiani.bsky.social · 26/01/2026Immigration is the issue on which Trump had the best approval ratings but is currently dragging his polls down 010
Marco Piani @marcopiani.bsky.social · 21/01/2026How are things going one year after, you ask? They are in the clear. Meaning, in the ratings graph there is a white gap between the disapproval band and the approval band. 010
Marco Piani @marcopiani.bsky.social · 18/08/2025Physicists: we should counter the impression that quantum mechanics is weird and inaccessible to ordinary people; anybody with sufficient interest and ready to put in the effort can learn quantum mechanics Also physicists: 150

Marco Piani @marcopiani.bsky.social · 25/04/2025Trump’s appeal to Putin sounds very similar to me turning off a ringing Alexa alarm. 040
Marco Piani @marcopiani.bsky.social · 24/04/2025There is a lesson here: if you Putin the effort, you can achieve a lot - like almost flipping the approval ratings - in a short time. 100
Marco Piani @marcopiani.bsky.social · 10/04/2025What some people do not seem to understand is that the U.S. under Trump has lost the trust of other countries and (further) damaged the status of leader of the Western World. It does not matter whether tariffs go / stay down. This is particularly true for Canada. 052

Marco Piani @marcopiani.bsky.social · 09/02/2025BREAKING In a meeting with top officials and the U.S. president, Musk has proposed to create a nuclear deterrent in the form of what appears to be called a “doomsday machine”. Details are lacking but a photo has leaked of him thanking the audience at the end of the meeting. 081
Marco Piani @marcopiani.bsky.social · 04/02/2025- Canada is still in some limbo, w tariffs just on hold - Canada must become more independent from the U.S., particularly given their capricious president - the relationship is damaged We are in a new phase of Canadian history Those stickers are more than labeling and will stay 2247

Marco Piani @marcopiani.bsky.social · 01/02/2025I have seen politicians claiming that Canada has a huge leverage on the U.S. as large importer of U.S. goods. I do not know whether they are fooling also themselves or only the public, as there is a enormous imbalance when it comes to the relevance of the exports of one country to the other. 200

Marco Piani @marcopiani.bsky.social · 08/01/2025It takes time – the migration time – to safely and correctly migrate cybersystems to quantum-safe solutions. Given that attackers can “Harvest Now, Decrypt Later” sensitive data, the fact that a CRQC is, say, 15 years away should not be cause for complacency. 100
Marco Piani @marcopiani.bsky.social · 08/01/2025… which in turn means that last polls have provided a consistent likelihood estimate in absolute time: ~2040 is roughly the time when you might consider that a CRQC begins to be more likely to exist than not. 100
Marco Piani @marcopiani.bsky.social · 08/01/2025When it comes to our polls, focusing on a stable set of respondents for the past three years and averaging the likelihood estimates, one finds that the average likelihood estimates have grown from survey to survey, when considering timeframes… 100
Marco Piani @marcopiani.bsky.social · 08/01/2025On the other hand, there are some important points to make. First, there is wide variability in the estimates of the pool of experts, which again reminds us of the challenge faced in developing quantum computers and of the unavoidable uncertainties. 100
Marco Piani @marcopiani.bsky.social · 08/01/2025… and this is an alternative view, where one can perhaps see more clearly the shift in the estimated likelihood, from timeframe to timeframe. 100
Marco Piani @marcopiani.bsky.social · 08/01/2025… we only consider relatively widely separated timeframes, while asking the expert to pick coarse-grained likelihood estimates, e.g. <1%, <5%, <30%, etc. This is a graph of the response distribution by timeframe and likelihood bin… 100
Marco Piani @marcopiani.bsky.social · 08/01/2025The core of the report – now in its sixth year! – is a survey of worldwide leaders and experts in the field of quantum computing research. 32 respondents participated in 2024. 110
Marco Piani @marcopiani.bsky.social · 08/01/2025Nvidia’s CEO Jensen Huang's comments yesterday about the timeframe for “very useful quantum computers” make today as good a day as any to share some points of the @gri and @evolutionq Quantum Threat Timeline Report for 2024, published in December. 230

Marco Piani @marcopiani.bsky.social · 04/12/2024Fun(?) fact: according to the estimates by Forbes, the four wealthiest billionaires together own assets that are worth more than a trillion USD. Also: you can quickly acquire approx as much wealth as Musk simply by having every living American give you 1,000 USD. Easy. 110
Marco Piani @marcopiani.bsky.social · 04/12/2024The “Canada Post Team team” is still hard at work! If you are not receiving mail and packages it is not because of some fictional strike. It’s more likely because of some bad zip code. 100
