Perhaps, classical physics has no role for consciousness. Quantum mechanics requires mind to set variables to observe {quantum mechanics, mind}.
Gödel Incompleteness
Halting problems prove that mind does not use algorithms. Mathematicians can understand non-computable-function truth, but computer programs cannot. Quantum computing can be non-algorithmic and non-recursive.
gravity
Wavefunctions collapse at large-scales by non-local gravitational process (objective reduction). Such gravitational effects happen in tenths of seconds and are not algorithmic.
microtubules
Perhaps, quantum mechanics affects nerve microtubules. However, time before quantum state decoherence is too short, 0.1 milliseconds or less [Grush and Churchland, 1995] [Hameroff and Penrose, 1996] [Hameroff et al., 1996] [Hameroff et al., 1998] [Lockwood, 1991] [Penrose, 1989] [Penrose, 1994].
Copenhagen interpretation
In Copenhagen quantum-mechanics interpretation, quantum mechanical laws specify what knowledge/information people can have about systems. Actions that gather information about relations among observations gain knowledge. Physical laws are not about reality, particles, or energy.
Classical systems use real numbers, whose operations are commutative, to specify particle and energy properties. Quantum-mechanical laws use complex numbers, with non-commutative operations, to specify dynamical-system changes and state/observation probabilities. Quantum-mechanical mathematical descriptions are about wave events rather than numbers.
events: Process 1
Observation causes wavefunction collapse and makes one of the possible states appear. Observations are conscious and/or psychological events. Mind must choose question to answer, observable to measure, and location and time to measure. Observation requires mind, which chooses what to observe by choosing experiment and observes directly or by instrument. Observations have experimental conditions and measurement variables, described the same as in classical physics, that instruments can communicate to people.
Observing systems, including measuring instruments, can be quantum mechanical or classical. Measuring instruments typically are classical, while atomic systems are quantum mechanical {Heisenberg cut}. Quantum-mechanical descriptions approximate continuous classical states with probabilities. Observable instrument states must be countable, and states have probabilities.
events: Process 2
System physical processes proceed according to mathematical laws, until another observation. Observed systems are quantum mechanical. Physical processes do not cause choices. Mathematical laws do not require choices.
Von Neumann
Brain, measuring apparatus, and physical system to measure are in one physical system. Brain chooses what to observe, the variable. In Process 1 {Heisenberg Choice}, observers choose variables to observe using consciousness. Variables are measurable and have specific discrete states. In Process 2, system evolves quantum mechanically, deterministically, and locally. Lengths and times become more uncertain. In Process 3 {Dirac Choice}, quantum jump puts variable in state and mind in knowing state.
quantum Zeno effect
Quantum effects only persist for 10^-13 seconds. However, in some physical conditions, making same observation process repeatedly at high-enough rate causes observations to repeat {quantum Zeno effect}. Experiment timing affects observed-state probabilities. Perhaps, in mind, attention is rapid probing and holds mental states for prolonged periods.
