Institut quantique has just released its newest Quantum Enigma – The Birthdays on YouTube : https://www.youtube.com/watch?v=g2ChaEAsO3E&t=1s
You are invited to a reception at Aïka’s house with your friends Bob, Charlie and Dahlia. At the door, you learn that Aïka has limited the number of people allowed. You must determine the minimum number of people so that there is more than a 50% chance that two people have the same birthday.
Classical problems solved in quantum circuits!
