I am always curious, so if i read the title "Quantum Algorithms in a Superposition of Spacetimes", i want to know what it's about. Sadly too complex for me😀 https://arxiv.org/abs/2403.02937 #quantum
Quantum sensor technology promises even more precise measurements of physical quantities. A team led by Christian Roos at the University of Innsbruck has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment.
Correlation spectroscopy can be used to increase the precision of sensor networks.
Apple wouldn't be doing this—at considerable expense—if they didn't consider such attacks to be plausible within the relevant lifetime of currently intercepted and retained messages (ie. not necessarily today, but within the statute of limitations of any crime you might be confessing to in an iMessage).
@cstross Agreed with the general premise, but a part of the justification might also be that they can then use this as a marketing #talkingpoint, that their systems are so much more secure than the competition, ahead of anyone else, and in line with the image they're trying to cultivate that people on iPhones don't get hit by viruses or trojans? #optics being everything these days it seems.
Starting a new thread for #quantumpoetry ...finding either #quantum research or #poetry that connects both fields. Starting with the opening lines from "Leaves of grass" by Walt Whitman from the first Edition 1855 . Clearly visionary for quantum entanglements. Note: Please boost for better visibility. #poetrycommunity#quantumphysics#physics#literature
@mkiol No question. It's certainly always important to seek alternatives. However, #Brave is one of the examples (#Vivaldi, #Edge, #Chrome, #Chromium, #Bromite …), which I find also troubling because at the end of the day, it's focused on just one rendering engine. These are then monopolies, which are often not good for the user. #Mozilla's is actually the only competitor currently regarding rendering engines (#Gecko, #Quantum) to Google (#Blink. #WebKit).
Nice to see some work on #Quantum Factoring algorithms, combining quantum circuits of smaller size with a “classical” lattice reduction post-processing step. Unclear what the practical impact is though since it's unclear that the optimizations to reduce the number of qubits required would still work because of the repeated squaring of Regev's paper. https://arxiv.org/abs/2308.06572
Another interesting result using a hybrid algorithm to do prime factorization:
"In particular, the number of qubits goes below the size of the RSA modulus, and for RSA-2048 we could propose a circuit with less than 1700 qubits. The space required for factoring will depend on the input register rather than the workspace register, as the latter
can be compressed down to size O(log n)" https://eprint.iacr.org/2024/222 #Quantum#QuantumComputing
This real life space mission reads like the beginning of the sci-fi movie (futurism.com)
The test involved IVO's quantum drive, a reactionless drive that supposedly doesn't need propellant to generate thrust
