Goal-directed navigation requires animals to continuously evaluate their current direction and speed of travel relative to landmarks to discern whether they are approaching or deviating from their goal. Striatal dopamine release signals the reward-predictive value of cues1,2, probably contributing to motivation3,4, but it is unclear how dopamine incorporates an animal’s ongoing trajectory for effective behavioural guidance. Here we demonstrate that cue-evoked striatal dopamine release in mice encodes bidirectional trajectory errors reflecting the relationship between the speed and direction of ongoing movement relative to optimal goal trajectories. Trajectory error signals could be computed from locomotion or visual flow, and were independent from simultaneous dopamine increases reflecting learned cue value. Joint trajectory error and cue-value encoding were reproduced by the reward prediction error term in a standard reinforcement learning algorithm with mixed sensorimotor inputs. However, these two signals had distinct state space requirements, suggesting that they could arise from a common reinforcement learning algorithm with distinct neural inputs. Striatum-wide multifibre array measurements resolved overlapping, yet temporally and anatomically separable, representations of trajectory error and cue value, indicating how functionally distinct dopamine signals for motivation and guidance are multiplexed across striatal regions to facilitate goal-directed behaviour.

The exceptionally low-energy isomeric transition in 229Th at around 148.4 nm (refs. 1,2,3,4,5,6) offers a unique opportunity for coherent nuclear control and the realization of a nuclear clock7,8. Recent advances, most notably the incorporation of large ensembles of 229Th nuclei in transparent crystals6,9,10,11 and the development of pulsed vacuum ultraviolet (VUV) lasers12,13,14, have enabled initial laser spectroscopy of this transition15,16,17. However, the lack of an intense, narrow-linewidth VUV laser has precluded coherent nuclear manipulation8,18. Here we introduce and report a continuous-wave (CW) laser at 148.4 nm, generated by means of four-wave mixing (FWM)19 in cadmium vapour. The source delivers more than 100 nW of power with a projected linewidth well below 100 Hz and supports broad wavelength tunability. This represents a five-orders-of-magnitude improvement in linewidth over all previous single-frequency lasers below 190 nm (refs. 12,13,14,20). We develop a spatially resolved homodyne technique that places a stringent upper bound on FWM-induced phase noise, thereby supporting the feasibility of sub-hertz VUV linewidths. Our work addresses the central challenge towards a 229Th-based nuclear clock and establishes a widely tunable, ultranarrow-linewidth laser platform for potential applications across quantum information science21,22,23,24, condensed-matter physics25 and high-resolution VUV spectroscopy26.

Quantum electrodynamics (QED), the first relativistic quantum field theory, describes light–matter interactions at a fundamental level and is one of the pillars of the Standard Model (SM). Through the extraordinary precision of QED, the SM predicts the energy levels of simple systems such as the hydrogen atom with up to 13 significant digits1, making hydrogen spectroscopy an ideal test bed. The consistency of physical constants extracted from different transitions in hydrogen using QED, such as the proton charge radius rp, constitutes a test of the theory. However, values of rp from recent measurements2,3,4,5,6,7 of atomic hydrogen are partly discrepant with each other and with a more precise value from spectroscopy of muonic hydrogen8,9. This prevents a test of QED at the level of experimental uncertainties. Here we present a measurement of the 2S–6P transition in atomic hydrogen with sufficient precision to distinguish between the discrepant values of rp and enable rigorous testing of QED and the SM overall. Our result ν2S–6P = 730,690,248,610.79(48) kHz gives a value of rp = 0.8406(15) fm at least 2.5-fold more precise than from other atomic hydrogen determinations and in excellent agreement with the muonic value. The SM prediction of the transition frequency (730,690,248,610.79(23) kHz) is in excellent agreement with our result, testing the SM to 0.7 parts per trillion (ppt) and, specifically, bound-state QED corrections to 0.5 parts per million (ppm), their most precise test so far.
