Today’s quantum computers are too rudimentary to do so. But data surreptitiously gathered now could still be sensitive when more powerful quantum computers come online in a few years. The computing industry is well aware of this potential vulnerability. Some companies have embarked on an effort to create, test and adopt new encryption algorithms impervious to quantum computers…
