Scientists make quantum time flow backward in stunning physics breakthrough Date: July 3, 2026 Source: Los Alamos National Laboratory Summary: Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow of time and even harvest energy from the measurement process itself. The breakthrough could lead to more powerful quantum computers, quantum batteries, and other advanced technologies. Share: FULL STORY Researchers Make Quantum Time Flow Backward Researchers have taken a major step toward reversing the quantum arrow of time—and discovered a surprising new way to harvest energy in the process. Credit: AI/ScienceDaily.com Scientists have developed a new way to control quantum systems that can make their behavior appear more consistent with time moving backward rather than forward. The research, published in Physical Review X, introduces quantum control protocols that reshape a system's "arrow of time," the concept that time naturally moves in only one direction. The approach could eventually support new methods for extracting energy from quantum systems and preparing quantum states. A quantum system, such as a group of qubits, follows the rules of quantum mechanics rather than classical physics. Using the newly developed control protocols, researchers can suppress the usual emergence of the arrow of time or even reverse its apparent direction, making quantum processes look as though they are unfolding backward. As a demonstration of the technique, the team also created a measurement engine that can harvest energy from the act of making quantum measurements. "Unlike phenomena we observe around us, at the microscopic level most fundamental laws of physics see forward and backward movement in time as physically possible," said Los Alamos National Laboratory physicist Luis Pedro García-Pintos. "In other words, those laws of physics are symmetrical under time reversal; the equations work just as well if you reverse time. For quantum systems, which operate at that microscopic level, the tools we've constructed can manipulate the perceived arrow of time, leading to surprising, novel ways to control quantum systems." Engineering Time Reversed Quantum Behavior In everyday classical physics, making a measurement has little effect on the object being observed. Quantum systems behave very differently. Measuring them randomly changes their state, naturally creating an arrow of time. To overcome that effect, the researchers combined measurements with feedback to produce time reversed stochastic trajectories. This allowed quantum systems to follow paths that appear consistent with time flowing in reverse. The team accomplished this by designing a control Hamiltonian, a carefully planned sequence of fields and pulses that reproduces the effects of quantum measurements. When incorporated into a feedback system, the Hamiltonian can cancel, strengthen, or even overcorrect the disturbances caused by measurements. As a result, the system can generate trajectories that correspond to stretched, blurred, or inverted arrows of time. A Quantum Version of Maxwell's Demon The work also builds on the famous 19th century thought experiment known as "Maxwell's demon." In that scenario, a hypothetical observer selectively sorts hot and cold particles, apparently reducing entropy and challenging the second law of thermodynamics, which states that entropy naturally increases or remains constant. (Later physics has shown that the second law is not violated when all sources of thermodynamic costs are accounted for.) The Los Alamos team's quantum "demon" uses information about a quantum system's state and measurement results to produce similarly unusual behavior, effectively reversing the system's natural arrow of time. Extracting Energy From Quantum Measurements The new control methods also allow researchers to influence how energy moves into and out of a quantum system. This capability could power a continuous measurement engine that extracts useful energy directly from the monitoring process. In this framework, quantum measurements become a thermodynamic resource that can be tapped to perform work, such as driving another quantum process or storing energy in a quantum battery. Looking ahead, the researchers plan to experimentally demonstrate Hamiltonian based measurement processes for quantum feedback control using superconducting qubits. These systems support rapid feedback, highly efficient detection, and have already been used to implement quantum versions of Maxwell's demon. Future studies will also apply the new techniques to develop improved quantum state preparation protocols.

For decades, the mainstream Jewish community and conservative Christians often found themselves on opposite sides of domestic cultural issues. However, the aggressive overreach of radical activist networks in public education has shattered old political divisions, forging an unprecedented, highly effective coalition [10.1].This unexpected alliance works in practice through three major common interests:1. A Shared Stand for Parent Rights and TransparencyThe underhanded tactics used to advance curricula like San Francisco’s Voices—such as midnight votes and copyright shields—alienated Christian families just as much as Jewish families.Breaking the Monopolies: Conservative and Christian legal networks have joined hand-in-hand with Jewish advocacy groups to mandate total educational transparency. They are deploying joint resources to demand that public school boards publish every single reading list and lesson plan online, permanently dismantling the ability of radical administrators to hide their work.Electoral Force: In suburban communities like Fremont and across Silicon Valley, Christian, Jewish, and immigrant parent groups (such as East Asian and Indian coalitions) are combining their voting power [10.1]. They are pooling campaign funds to systematically remove radical progressive officials from local school boards and replace them with moderate, transparency-first candidates.2. Uniting Against the "Oppressor vs. Oppressed" FrameworkTraditional Christians and Jewish advocates share a fundamental rejection of radical identity-based theories that divide children into rigid moral categories based on race or religion.Defending Basic Values: Both communities view the "Liberated" framework as an assault on universal values, meritocracy, and individual character. Christian parents refuse to let their children be taught that their faith or traditional values are inherently oppressive, while Jewish parents refuse to let their children be targeted by biased political dogmas.3. Bipartisan Legislative and Federal EnforcementThis alliance has successfully elevated local school board grievances into historic federal and state-level protections.The Right to Worship Act: Just days ago, on August 6, 2026, a major bipartisan, bicameral coalition led by Senator Ted Cruz (R-TX) and Representative Tom Suozzi (D-NY) introduced the federal Right to Worship Act. Backed heavily by the Anti-Defamation League (ADL), this bill establishes strict 100-foot protective buffer zones and heavy civil fines to stop hostile activist crowds from blockading or harassing congregants outside houses of worship.The Federal Crackdown: The Trump administration’s upcoming 15-city DOJ task force and FBI deployment is heavily cheered by red-state conservatives. They view the federal audits into deep-blue California municipalities as the ultimate enforcement of civil rights, proving that local progressive immunity expires where federal law begins.The progressive establishment completely miscalculated. They assumed they could isolate Jewish families by using anti-racist language, but their reliance on secrecy and radical tactics instead forced a historic real-world alignment. Mainstream Jews, traditional Christians, conservatives, and diverse immigrant communities have formed a massive, united front—permanently forcing the radical movement into a corner as the legal guardrails close in [10.1].

According to the Anti-Defamation League (ADL), American antisemitism remains at historically high levels, with 57% of American Jews reporting that antisemitism has become a normal part of daily life. While tracking shows high volumes of harassment, vandalism, and assaults nationwide, recent data also indicates targeted institutional progress and legislative pushback.Campus Climate and ProgressReport Card Improvements: The ADL's Campus Antisemitism Report Card evaluated 150 universities in 2026, showing that 61% earned top grades (A or B), up significantly from 23.5% in 2024.Ongoing Student Impact: Despite administrative policy updates, 48.3% of non-Jewish and Jewish students surveyed reported witnessing or experiencing anti-Jewish behavior on campus or digital spaces.Persistent Incidents: Pockets of activism, intermittent encampments, and vandalism continue to challenge campus administrators despite increased cooperation with the ADL.Public Safety and Legislative EffortsSynagogue and Community Threats: Houses of worship face continuous pressure, leading advocacy groups to push for robust federal funding through the Nonprofit Security Grant Program.Bipartisan Bills: Lawmakers introduced measures like the Jewish American Security Act—welcomed by the ADL—to mandate online transparency for major social media platforms regarding hate speech and antisemitic content metrics.Major InitiativesNever Is Now Summit: The ADL hosted its annual Never Is Now gathering, drawing thousands of participants to strategize on combating modern political and social antisemitism.
