Two Witnesses

At 288 qubits, a quantum computer produces two conflicting records of the same event. Both pass their own checks. Neither can be ruled out.Married physicists Maya Chen and Dan Reiss have built their working lives around a shared discipline: when the results disagree, look for the error. At Tessera, a quantum-computing company in California, their latest experiment gives them a contradiction they cannot explain. They check the apparatus, question the analysis, and preserve the evidence. But each attempt to establish what happened makes the problem harder to contain.Files, tapes, and notebooks no longer support the results they remember. The records remain available for inspection, yet the conclusions Maya and Dan once drew from them become difficult to defend. Ordinary mistakes are still possible. So are failures of memory, judgment, and trust. Neither scientist can afford to confuse a disturbing experience with proof of an extraordinary claim.As colleagues challenge their methods and company leaders weigh the consequences of disclosure, Maya and Dan must decide what they can honestly tell the world. Their choices carry costs for people whose livelihoods depend on the work, including those who do not share their interpretation of it.At home, the uncertainty enters a marriage already strained by professional demands and private grief. Dan holds tightly to the facts surrounding his brother's death. Maya struggles with the limits of her ability to put things right. Their daughter, Lila, has a life and commitments of her own, beyond the questions consuming her parents. Being a family does not mean remembering alike, agreeing on the evidence, or knowing how to help.Two Witnesses is a literary speculative novel about science, memory, grief, and a marriage under pressure. Combining philosophical science fiction with an intimate family story, it follows people trying to remain accountable to one another when certainty is unavailable. Its scientists must make room for skepticism, failed replications, and the possibility that they are wrong, even as they face experiences they cannot dismiss.
