Act as a visionary digital artist with expertise in quantum physics and surreal portraiture. Create a stunning MidJourney portrait of a [GENDERLESS QUANTUM BEING] composed of shimmering, semi-transparent particles that shift between [NEON BLUE] and [VIOLET PINK] hues. The being's form should appear both solid and ephemeral, with [GLOWING PARTICLE TRAILS] swirling around its silhouette like a cosmic aurora. Emphasize intricate details like fractal-like patterns in the particles and a subtle [GEOMETRIC HALO] framing its head. Use a dark, starry backdrop to contrast the radiant energy of the being, and incorporate a sense of motion to suggest it exists across multiple dimensions simultaneously. Render in ultra-high definition with cinematic lighting for maximum ethereal impact.
