Note in the hotel room that says: "Note that our rooms are equipped with an Air Climate Control system (not air conditioning) which is linked to the outside temperature. We understand it may not suit all our guests so portable heaters or fans are available on request."
Screenshot of google scholar showing Lov Grover, with only one paper: the paper that introduced Grover search, with 15,542 citations.
Screenshot of the final stanza of the poem, ending in "by machines of loving grace. Below that is: "Analysis (ai): The poem presents a utopian vision where technology and nature coexist seamlessly, suggesting..."
Screenshot of the Atlantic. Headline: I found it: the best free restaurant bread in America
A cluttered and complicated chart relating qubit counts to qubit error rates, comparing today's devices to cryptographic attacks.
Photo of a piece of cardboard with a hexagonal grid, rules handwritten on looseleaf, cardboard pieces, and a box of mini wheats labelled "Settlers of Catan"
Screenshot of comments in code. They say: Dear programmer: when I wrote this code, only God and I know how it worked. Now, only God knows it! Therefore, if you are trying to optimize this routine and it fails (most surely), please increase this counter as a warning for the next person. Total hours wasted here = 254
Graph of physical qubits vs. year. There is a cluster of points in the middle, with 3 lines trying to extrapolate forward, but with wide error margins.
Figure 14 from Gidney's paper showing a dense 3-d pipe diagram of a surface code layout of a lookup. Most of the 3-d space is used in some way.
A chart for quantum computers, of number of qubits versus error rate, on a logarithmic scale. Broadly it shows a large gap between current quantum computers in the bottom left, and a curve in the top right of the resources they need to break RSA.
Screenshot of "tenderhomeassist.com". It reads "Using a steamer app: There are also several steamer apps available for smartphones and tablets. These apps emit a stream of hot air that can be used to steam iron clothes. Simply download the app and follow the instructions to use it"
Fishing hat embroidered with "couches what me, popes fear me"
Screenshot of "have I been pwned" with "Pete.hegseth@foxnews.com" showing that he has been pwned
A mouse on a table with a paper sign "please use this mouse to control the map screen". The mouse cable leads into a dark room behind a door which is slightly ajar
A chart of quantum computing comparing number of qubits to error rate. This is a very visual chart and is better explained in text on my website.
Graph from Google's blog post about Willow, a graph of difficulty versus usefulness, with random circuit sampling right near zero usefulness
Gif of Hans Moleman from the Simpsons during the attack of birds, saying "I need the biggest prime number you have. No, that's too big"
Graph from the new google paper showing the physical error rate (approximated by "mean detection probability") versus the logical error rate, showing that at higher distances, the logical error rate is lower, but only if the physical error rate is below a threshold.
A graph showing what's described in the tweet: it shows the probability of logical error in each surface code cycle. All of these are increasing lines, but the line for distance 5 grows much slower than distance 3, and distance 7 grows much slower than distance 5.
