The Nintendo Switch may be remembered as much for repopularizing portable gaming as it will for a hardware issue that affected millions of gamers: joystick drift. Drifting is the most common term for an issue where joysticks detect false inputs — even when no one is touching a controller — causing unwanted movements to happen in a game. The issue also affects controllers from Sony, Microsoft, and third-party accessory makers. Hall effect sensors emerged a few years ago as a potential solution to the problem, but there’s an even better option out there that’s easier to retrofit into existing controller designs. That solution is tunneling magnetoresistance, or TMR, a technology that revolutionized hard drives two decades ago using quantum mechanics and magnets.

A critical vulnerability arises from basis-dependent detection probabilities, which can be exploited by an adversary. This study presents a rigorous security proof that relaxes the standard assumption of basis-independent detection probabilities, by developing a framework to quantify efficiency mismatches online and adjust the key rate accordingly. The approach ensures positive key rates in honest cases, detects and mitigates adversarial attacks that go unnoticed in conventional analyses, and shows how prior proofs may have been overly pessimistic.

Opinion by: Dr. Michael Tabone, senior economist for CointelegraphBitcoin (BTC) has long been hailed as unbreakable and untouchable, a digital stronghold against the forces of change. Bitcoin’s bedrock of security is facing its first true test with quantum computing, which should be addressed sooner rather than later. Its cryptographic armor will crack if not addressed, forcing the network to adapt or perish. Bitcoin’s node count is growing, but incentives are still absentBitcoin’s full node network has grown over time, a sign of increasing adoption and a more robust infrastructure, but the core issue remains. The voluntary act of running a node still has no financial incentive.
