Quantum Computers Face Serious Security Risks
Quantum computers are very powerful and can do things regular computers can't, like helping scientists find new medicines faster.
But they also have big security problems.
Researchers say these computers can be hacked or messed up in ways that regular computers aren't.
They need special protection from the very beginning, not just with software but also at the hardware level.
Right now, companies are working to make quantum computers reliable, but they're not focusing enough on keeping them safe.
This could be a big problem in the future as these computers become more common in important industries.
Quantum computers face serious security risks due to their powerful processing capabilities.
Researchers recommend safeguarding quantum computers at the device, circuit, and system levels.
Current cybersecurity techniques for classical computers are ineffective for quantum systems.
Commercial providers are focused on reliability rather than security in quantum computers.
Interconnected qubits and crosstalk can leak information or disrupt computations.
