      abstract     = {Radio-frequency (RF) accelerators providing high-quality
                      relativistic electron beams are an important resource
                      enabling many areas of science, as well as industrial and
                      medical applications. Two decades ago, laser-plasma
                      accelerators1 that support orders of magnitude higher
                      electric fields than those provided by modern RF cavities
                      produced quasi-monoenergetic electron beams for the first
                      time2,3,4. Since then, high-brightness electron beams at
                      gigaelectronvolt (GeV) beam energy and competitive beam
                      properties have been demonstrated from only centimetre-long
                      plasmas5,6,7,8,9, a substantial advantage over the hundreds
                      of metres required by RF-cavity-based accelerators. However,
                      despite the considerable progress, the comparably large
                      energy spread and the fluctuation (jitter) in beam energy
                      still effectively prevent laser-plasma accelerators from
                      driving real-world applications. Here we report the
                      generation of a laser-plasma electron beam using active
                      energy compression, resulting in a performance so far only
                      associated with modern RF-based accelerators. Using a
                      magnetic chicane, the electron bunch is first stretched
                      longitudinally to imprint an energy correlation, which is
                      then removed with an active RF cavity. The resulting energy
                      spread and energy jitter are reduced by more than an order
                      of magnitude to below the permille level, meeting the
                      acceptance criteria of a modern synchrotron, thereby opening
                      the path to a compact storage ring injector and other
                      applications.},
