![]() ![]() Spin defines how the electrons interact with a magnetic field, in the same way that charge defines how electrons interact with an electric field. In the same way that electrons have mass and charge, they also have a quantum property called spin. In my work, I build instruments to study and control the quantum properties of small things like electrons. Studying quantum mechanical effects in biology requires tools that can measure the short time scales, small length scales and subtle differences in quantum states that give rise to physiological changes – all integrated within a traditional wet lab environment. The tantalizing possibility that subtle quantum effects can tweak biological processes presents both an exciting frontier and a challenge to scientists. Research suggests that quantum effects influence biological functions, including regulating enzyme activity, sensing magnetic fields, cell metabolism and electron transport in biomolecules. Importantly, such nanoscopic, short-lived quantum effects are consistent with driving some macroscopic physiological processes that biologists have measured in living cells and organisms. Research on basic chemical reactions at room temperature unambiguously shows that processes occurring within biomolecules like proteins and genetic material are the result of quantum effects. In a complicated, noisy biological system, it is thus expected that most quantum effects will rapidly disappear, washed out in what the physicist Erwin Schrödinger called the “ warm, wet environment of the cell.” To most physicists, the fact that the living world operates at elevated temperatures and in complex environments implies that biology can be adequately and fully described by classical physics: no funky barrier crossing, no being in multiple locations simultaneously.Ĭhemists, however, have for a long time begged to differ. For example, an electron can be manipulated to be in two places at the same time, but it will end up in only one place after a short while – exactly what would be expected classically.Įlectrons can be in two places at the same time, but will end up in one location eventually. ![]() Everything that starts quantum dies classical. In other words, a macroscopic collection of quantum objects is better described by the laws of classical mechanics. This is because quantum objects like atoms and molecules lose their “quantumness” when they uncontrollably interact with each other and their environment. In general, quantum effects only manifest at very small length and mass scales, or when temperatures approach absolute zero. In fact, you already live in a quantum-powered world: from laser pointers to GPS, magnetic resonance imaging and the transistors in your computer – all these technologies rely on quantum effects. Researchers can manipulate quantum phenomena to build better technology. It also means that we could possibly control physiological processes by using the quantum properties of biological matter. If this is indeed true, it means that our understanding of biology is radically incomplete. However, and somewhat surprisingly, there is increasing evidence that nature – an engineer with billions of years of practice – has learned how to use quantum mechanics to function optimally. Research in quantum mechanics is usually geared toward technology. cellophane) sleeve and mailed in a stay flat rigid mailer.I am trained as a quantum engineer.
