(a) Tomographic precision Fp(N,ρideal) for ρideal = |ϕ+〉〈ϕ+| with | ϕ + = 1 2 ( | H H + | V V ). Each data point represents a 2000-tomography numerical Monte Carlo simulation of the average fidelity between the reconstructed density matrix and ρideal, under realistic assumptions about the system noise (a coincidence-to-accidental ratio of 3). Each simulated tomography utilizes four detectors and nine coincidence measurements, such that each unknown quantum state in the N-state ensemble is projected onto one of nine four-element orthonormal bases (e.g., HH, HV, VH, VV). Results for both the maximum likelihood technique and the truncated-eigenvalue, linear-least-squares-fit technique are shown. For a given N, the maximum likelihood technique is slightly more precise [16]. (b) Using the same simulated data, Fp is shown as a function of total tomography time T for two different experimental systems: a traditional free-space tomography system with η = 0.1, τs = 5 s, τa = 5 s and an entangled photon polarimeter with η = 0.07, τs = 0.02 s, τa = 0.001 s. In both systems R = 106 pairs/second and M = 9.

Selected frames from the nine fps video of a two-qubit photon state’s transition from separability to entanglement ( Media 1). Each frame shows a density matrix reconstructed using the previous 36 measurements (≈ 4 s of data). Similar videos show non-transitioning separable ( Media 2) and maximally entangled ( Media 3) states. (All videos at 3x speed).
