IBM quantum processor generates 1 million samples in 19 seconds in random circuit sampling test

IBM\'s quantum processor Nighthawk r2 generated 1 million samples in 19 seconds in a random circuit sampling test used to assess quantum advantage. A research team led by Tigran Sedrakian at U.S. quantum software company BlueQubit released a preprint describing the experiment. The team estimated the same task would take about 110 years on a state-of-the-art supercomputer. The report cautioned the result applies only to the specific benchmark and has not yet undergone peer review.

Bitcoin may shift from 4-year halving cycle to Wall Street-style 6-8 year rhythm

Bitcoin may be moving away from its traditional four-year halving-led cycle toward a Wall Street-style 6 to 8-year rhythm, an analysis said. Analyst Willy Woo said institutional money and macro liquidity are increasingly shaping prices, making bitcoin closer to traditional short-term debt cycles. He said the halving impact is weakening as new supply shrinks, while institutional holdings now exceed miners’ annual output many times over, potentially shifting future turning points.

Samsung Electronics, SK Hynix diverge on long-term memory contract strategy

Samsung Electronics and SK Hynix are shifting memory sales to multi-year long-term supply agreements, but are taking different approaches. Samsung is seeking to lock in 60 to 70 percent of capacity under contracts that fix price and volume. SK Hynix is building up deals but keeping part of output outside contracts, citing supply constraints. With terms undisclosed, the outcome is expected to be judged by earnings and shareholder returns.
