Is your password safe from quantum computers?

  1. 1PW

    I wanted to make the simplest app to introduce myself and others to quantum computing. Introducing, Schrödinger's Coin. Powered by a simple Hadamard gate[0] on IBM quantum, with this app you can directly interact with a quantum system to experience true randomness. Thoughts? Could you see any use cases for yourself of this? Or, does it inspire any other ideas of yours? Curious what others on HN think! [0] https://en.wikipedia.org/wiki/Quantum_logic_gate#Hadamard_ga...

    Hey HN! I've created a quantum coin flip demo leveraging IBM's quantum computing tech to explore true randomness. It's a primer on into how quantum mechanics can solve classical computing's randomness limitations, crucial for cryptography and secure systems. Would love your thoughts on its application and quantum computing's future role in tech!

    Hi! I built this to teach myself how a quantum circuit simulator works. It's about 1000 lines of Python, aiming to be understandable more than being fast or robust. It's not meant to compete with anything else - just a personal project to really get clear on the under-the-hood theory of qubits and quantum gates.

    Hey HN! I made a service to share passwords easy and secure but never promoted it. It's called instapass.io I noticed that people besides my friends and clients actually started to use, so maybe it will be helpful for you too! You share one-time self-destruct message using one time links and I won't even be able to see what you wrote. How does it work? When you generate a message the client-side makes a random password and use that to encrypt the message. The password is appended as an anchor tag which all modern browsers never send to the server. This way, I don't even know what you shared.…

    Hey HN. I'm Colton (YC S21, ex-Acorns), one of the founders of Postquant Labs. My cofounder Richard is a cryptographer out of Draper Labs and DARPA. We're building Quip.Network, the first distributed quantum compute network. We just opened our testnet and wanted to share it here. The basic problem: quantum hardware is here and already competitive on certain optimization problems, but for most people, there's no way to access it. The machines cost millions and the hardware and research are gated by the companies who own them. Also, quantum providers regularly have machines sitting idle…

    Recently I became interested in knowing whether the passwords I used were in the list of breached passwords. One way to find out is to send your password to the link here https://haveibeenpwned.com/Passwords. However, while the owner of that website is a well respected security researcher, I still don't think it's wise to send my password to another website. So I downloaded the 24gb file, hashed my password and grepped the file for it. That unfortunately took a long time and I realized this was the perfect opportunity to use a BloomFilter and test the inclusion of a password…
