We demonstrate a vector magnetometer that simultaneously measures allCartesian components of a dynamic magnetic field using an ensemble ofnitrogen-vacancy (NV) centers in a single-crystal diamond. Optical NV-diamondmeasurements provide high-sensitivity, broadband magnetometry under ambient orextreme physical conditions; and the fixed crystallographic axes inherent tothis solid-state system enable vector sensing free from heading errors. In thepresent device, multi-channel lock-in detection extracts themagnetic-field-dependent spin resonance shifts of NVs oriented along all fourtetrahedral diamond axes from the optical signal measured on a single detector.The sensor operates from near DC up to a $12.5$ kHz measurement bandwidth; andsimultaneously achieves $\sim\!50$ pT/$\sqrt{\text{Hz}}$ magnetic fieldsensitivity for each Cartesian component, which is to date the highestdemonstrated sensitivity of a full vector magnetometer employing solid-statespins. Compared to optimized devices interrogating the four NV orientationssequentially, the simultaneous vector magnetometer enables a $4\times$measurement speedup. This technique can be extended to pulsed-type sensingprotocols and parallel wide-field magnetic imaging.
