Quantum attacks worry computer scientists
In the weird world of quantum computing, the state of computer systems networked together is so fragile that a read access to a single quantum bit, or qubit, on one machine would require a network-wide reset.
It's no wonder, then, that two researchers who are working on ways of defending against the future possibility of malicious attack assume that any unauthorised access to a quantum computer constitutes a catastrophic failure.
At The Register.
