LSU physicists create room-temperature quantum material for light manipulation

Researchers at Louisiana State University have developed the first quantum material that can sort and transport different quantum states of light at room temperature, eliminating the need for ultra-cold cryogenic refrigeration systems. The breakthrough, published in Nature, uses a gold metacrystal with engineered microscopic structures to achieve quantum effects previously only possible near absolute zero.

  • First room-temperature quantum material demonstrated, published in Nature
  • Gold film carved with hundreds of microscopic structures acts as quantum light filter
  • Addresses major barrier in quantum materials research—heat-induced disruption of quantum effects
  • Potential applications: quantum computers, secure communication, advanced sensors, energy technologies

India's RDI fund controversy: 62% of first disbursement goes to firms tied to selection panel members

India's government cleared ₹2,192 crore ($263 million USD equivalent) in soft loans from its ₹1-lakh-crore Research, Development and Innovation Fund to 22 companies, but 62% of the money went to 15 firms with financial ties to selection committee members, raising governance concerns about conflict of interest in public capital allocation.

  • ₹2,192 crore (62% of first disbursement) went to companies linked to panel members
  • Nine companies tied to committee chairman; one holds his personal equity stake
  • 124 applications received; 22 selected by 12-member Investment Committee
  • Government claims selections were merit-based; panel members used recusal procedures
