To truly wrap one’s head around entropy requires taking some deeply uncomfortable philosophical leaps. What is the purpose of science if physical qualities only make sense in relation to the observer?

What Is Entropy? A Measure of Just How Little We Really Know. | Quanta Magazine

Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world than a reflection of our growing ignorance. Embracing that truth is leading to a rethink of everything from rational decision-making to the limits of machines.

Why do quantum computers make terrible stand-up comedians?
Because their timing is always uncertain, and they never know if they’ve killed or bombed until the audience reacts 😜

Hello Quantum people, question here from a very non-quantum person.
Have heard around the place that quantum computing will be able to hack cryptography in the future. Is this an existential threat to Blockchain? If yes, why is no-one in the Blockchain world talking about it??

What is stopping us from launching quantum computers into deep space, where the operating temperature is already near 0 Kelvin? 🤔

TL;DR: it seems like temperature controlled QCs are colder than outter space. 😯

The current level of quantum computers has clear limitations such as high gate error rates and small number of physical qubits. For this reason, research on noisy-intermediate-scale quantum operation is being actively carried out. ⚛

Resource analysis and modifications of quantum computing with noisy qubits for elliptic curve discrete logarithms - Scientific Reports

We estimate the number of physical qubits and execution time by decomposing an implementation of Shor’s algorithm for elliptic curve discrete logarithms into universal gate units at the logical level when surface codes are used. We herein also present modified quantum circuits for elliptic curve discrete logarithms and compare our results with those of the original quantum circuit implementations at the physical level. Through the analysis, we show that the use of more logical qubits in quantum algorithms does not always lead to the use of more physical qubits. We assumed using rotated surface code and logical qubits with all-to-all connectivity. The number of physical qubits and execution time are expressed in terms of bit length, physical gate error rate, and probability of algorithm failure. In addition, we compare our results with the number of physical qubits and execution time of Shor’s factoring algorithm to assess the risk of attack by quantum computers in RSA and elliptic curve cryptography.
