The quantum Zeno effect is a quantum mechanical phenomenon first predicted by soviet physicist Leonid Khalfin in 1958.^[1] Later it was described by George Sudarshan and Baidyanaith Misra of the University of Texas in 1977.^[2] It describes the situation in which an unstable particle, if observed continuously, will never decay. This occurs because every measurement causes the wavefunction to "collapse" to a pure eigenstate of the measurement basis. In the context of this effect, an "observation" can simply be the absorption of a particle, with no observer in any conventional sense.
