    "abstract": "We present a method of measuring the quantum state of a harmonic oscillator\nthrough instantaneous probe-system selective interactions of the\nJaynes-Cummings type. We prove that this scheme is robust to general\ndecoherence mechanisms, allowing the possibility of measuring fast-decaying\nsystems in the weak-coupling regime. This method could be applied to different\nsetups: motional states of trapped ions, microwave fields in cavity/circuit\nQED, and even intra-cavity optical fields.",
