Can Bitcoins Frozen Due to Quantum Countermeasures Be Recovered?

On the 9th, BitMEX Research, the research division of the cryptocurrency exchange BitMEX, announced new countermeasures for Bitcoin (BTC) in preparation for the threat posed by quantum computers. The report detailed methods for safely recovering Bitcoins that could potentially be frozen if quantum computers become operational. Quantum computers possess computational capabilities far exceeding those of conventional computers and could potentially break the cryptographic technologies currently used by Bitcoin. In response to this risk, some experts have proposed a 'quantum freeze' measure to freeze Bitcoins at 'quantum-vulnerable' addresses...
