Quantum computing has long occupied the edges of our collective imagination – frequently mentioned, rarely understood. For many, it remains a distant prospect rather than an immediate concern. But that mindset is fast becoming a risk in itself.

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based spin qubits make it a promising material for scalable quantum computing.

Quantum computers are developing more quickly than expected – and so is the threat to our current computer security

What once took up the entire space of IBM’s early computer lab now fits on a chip. The question is how and when will the world develop quantum on a chip.

BTC quantum risk may affect around 6.7M coins, based on wallet type estimates. Google has predicted quantum attacks may happen before 2030.
